Bellacartwrightia whiteleyi trilobite uncovered by Alasdair Gilfillin at Penn Dixie in 2016.

Every so often, one of our visitors uncovers a truly spectacular fossil. The preservation might be perfect, the assemblage of different fossils might be unique, or the type of fossil might be very uncommon. In this case, we present a beautifully preserved and uncommon trilobite called Bellacartwrightia whiteleyi.

Penn Dixie member Alasdair Gilfillan discovered this trilobite at our park on October 3, 2016. Our dig season was coming to a close and Alasdair decided to spend a weekend visiting us from New Jersey. Alasdair dug into the infamous Smoke Creek trilobite bed of the Windom Shale and unearthed what he thought was a Greenops — an uncommon trilobite that seems to represent one or two of every 100 or so trilobites that are found. Instead, Alasdair found something much rarer. He writes:

You may remember that I found a nice (though at the time partially covered) trilobite which I thought was a Greenops that day. I managed to get it prepped and it turns out that it was a Bellacartwrightia, a much rarer form. The prep guy did a really nice job and it turned out to be a really fantastic specimen. Please find enclosed the photographs. The trilobite is ~ 1.5 inches long.

Alasdair adds that the prep work was done by Bob Miles — a former Penn Dixie board member who also took the photographs. We thank Alasdair for sharing his images and for his donation of many fossil specimens that were used in our school programs.

The Bellacartwrightia cephalon (head) resembles that of Greenops, but the two genera are not closely related.

Bellacartwrightia whiteleyi is uniquely found in the Devonian rocks of the Hamilton Group in New York State. This fossil was first described by Lieberman and Kloc in 1997; the original paper can be downloaded here. Bellacartwrightia was named after the wife of paleontologist Bruce Lieberman, who at the time was a postdoctoral fellow at the American Museum of Natural History. Dr. Lieberman is now at the University of Kansas. The paper explains how Bellacartwrightia is different from Greenops, another trilobite with a somewhat similar appearance. From page 29:

In addition, the members of this genus are phylogenetically distant from species assigned to true Greenops…These two Middle Devonian genera have not shared acommon ancestor since, at latest, the Siegenian [approx 411 million years ago], based on an analysis of ghost lineages. To treat these species as members of a genus Greenops would necessitate placing all of the asteropyginines within the genus Greenops.

There you have it — a new genus of trilobites first documented in 1997 and one of our members finds an excellent specimen 20 years after the discovery!

Alasdair was kind enough to share additional photos of the Bellacartwrightia as well as some of his other treasures from Penn Dixie. Our visitors are welcome to keep any fossils that they find, but we do appreciate photos of particularly cool fossils for use on our website.

The award!

Our nomination excerpt:

Penn Dixie is a community-based organization that would not exist without the support of the Hamburg Town Board and local businesses, schools, and families. Our fossil park — a unique treasure itself — draws tourists most of the year. In 2016, we welcomed nearly 15,000 visitors — many from outside the area — who stayed in Hamburg while visiting. Our annual Dig with the Experts weekend in May, for instance, generates an estimated $30,000 economic impact. Our park is very fortunate to receive incredible publicity which continuously brings positive attention to Hamburg.

The Tangled Web of Life

Ecologists study how organisms interact with their environment; however this can be quite difficult as a result of how messy life really is. Organisms interact in multiple ways, not only within their own species (two male deer fighting), but with other species (a snake squeezing a mouse) and their environment (a turtle basking on a log) which includes abiotic factors such as sunlight, wind, and water. What specific ways do animals interact with one another? Well they can compete, avoid predation, forage for food, seek shelter, disperse to other areas and it can be even more complicated when animals interact with humans! Humans are a major force that influences where organisms are located and what resources are available to them.

Figure 2: A monarch butterfly (Danaus plexippus) foraging on swamp milkweed (Asclepias incarnate). Photo by Amanda K. Martin.

Looking at foraging, there are two main types of organisms: producers and consumers. Producers are able to make their own food, these are plants. Through a process called photosynthesis, plants are able to convert sunlight into energy (ATP). By creating their own food, plants do not need to disperse or travel to other areas to eat. However, consumers are unable to make their own food, they must forage or travel to locate their food and eat it in order to obtain energy. There are different types of consumers: herbivores, omnivores, and carnivores. Herbivores consume plant material in order to survive. Herbivores such as monarch butterflies, deer, and muskrats forage for plants and consume either pieces or all of the available plant. Omnivores are animals that consume both plants and animals (meat) such as turtles, humans, and raccoons. Finally, carnivores consume only meat, they do not eat plants. These animals are at the top of the food chain such as hawks, snakes, and lions.

Figure 3: Without regulation from a predator, deer populations can explode and have negative impacts. Photo by Amanda K. Martin.

The available food resources are based on a pyramid, where the most abundant food resources are plants, fewer herbivores, less omnivores, and finally a small amount of carnivores. If the abundances of any category increase above carrying capacity, then the ecosystem will fall apart. For an example, when wolves were removed (extirpated) from Yellowstone, elk populations skyrocketed. This in turn reduced available plants, the elks overgrazed and other herbivores were unable to forage for food because there were too many elks. With the reintroduction of wolves, the elk population decreased and the system was once again balanced. A positive side effect of the reintroduction of the wolves was the increased grizzly bear population because there were available elk carcasses to consume.

Figure 4: A Northern water snake (Nerodia sipedon) resting in a leaf pile. Photo by Amanda K. Martin.

The food web is composed of many food chains (a linear flow of energy from one organism to the next). For an example, sunlight provides energy for vegetation, the muskrat eats the vegetation, while the snapping turtle can eat small muskrats, and finally the great blue heron eats the snapping turtle. This is a food chain for which each organism is one link in a chain. Food webs are created when multiple food chains are put together for which more organisms interact with one another. Not only does the great blue heron eat snapping turtles, but it can eat muskrats or water snakes, whereas the water snake could eat the muskrat. Each organism is linked together and when humans impact their environment, it can alter the food web. Some organisms can replace other lost species; however we do not know the true impact of our actions typically until it’s too late. By preserving or protecting habitat, we can reduce negative effects on multiple species!

Earth Science Day 2016

While Penn Dixie may be covered in ice and snow, we can always think ahead to the coming spring and summer months when the site will be visited by fossil collectors of all ages and experience levels. This spring, we’ve got Earth Day on April 22 and Dig with the Experts scheduled for Memorial Day weekend, plus many school field trips. In the summer we’ll host a full array of science and nature programs, but fall will be a really special time when we host our 20th Annual WNY Earth Science Day on Saturday October 7. To get in the sprit, take a look back at Earth Science Day 2016 — Saturday October 8 — with some photos courtesy of superstar volunteer Jake Burkett and his family.

Despite the chilly and wet morning, exhibitors and visitors who chatted under the big tent stayed mostly warm and dry.
The drill rig demonstration got a bit muddier than usual.
UB Geology might have brought the messiest activity: goupy glaciers that flowed through 3D models.
By late morning the skies cleared and our fossil collecting was in full swing.
These folks came down from Ontario and were very eager to find the perfect trilobite.
At just the right time, LLoyd Taco Truck arrived and satisfied the hungry lunch crowd — even T-rex.

Penn Dixie awarded grant for new astronomy programming

The Hamburg Natural History Society, which governs the Penn Dixie Paleontological & Outdoor Education Center in Hamburg, NY, is pleased to announce an award of $3,875 from Ronald McDonald House Charities of Western New York.

The grant will be used to purchase telescopes and microscopes towards the development of new astronomy programming at the Penn Dixie Site. The programming will augment existing volunteer-based efforts and will support the creation of new, hands-on science activities. These programs will be open to the public and local K-12 and scout groups.

The award will also add a digital projector, screen, and power stations for microscopes to Penn Dixie’s outdoor classroom. Given new capabilities, Penn Dixie will now be able to create an outdoor science lab that will be ideal for hands-on inquiry investigations of the natural world. Additionally, the grant will be used to develop culturally relevant astronomy programming for local Native American students.

The grant monies used to support this award were raised through the efforts of the local McDonald’s restaurants in the Western New York community, and in part by national McDonald’s promotional programs. Ronald McDonald House Charities provides lodging, comfort and emotional support to families of children receiving medical treatment at area hospitals, and reaches out to families in the community by supporting programs that benefit children.

By the numbers: 2016 attendance

A closer look at our 2016 attendance by HNHS/Penn Dixie Executive Director Dr. Phil Stokes

Penn Dixie’s 2016 May to September general admissions.

We’ve received a lot of feedback about our huge boost in attendance this year. While much of the feedback is positive, there’s some genuine curiosity as well. So, I thought that I’d share some of our strategies with our supporters. First, some notes:

  1. These data only represent general admissions (i.e., visitors who arrived at the site to collect fossils as individuals or small groups). We did not include group programs (e.g., school tours, scout programs), special events (e.g., Dig with the Experts), summer camps, lectures, off-site programs (e.g., Science Nights) and other programming.
  2. We estimated 2014 attendance as these numbers were not digitally available at the time we made our graph.
  3. A more detailed look at our 2016 attendance will be included in our annual report, which will be released this winter.

Onto the discussion

Looking back at our historical attendance, the number of visitors to our site steadily increased throughout the 1990s and 2000s. This was an important time for us — we were an all-volunteer organization for our first decade and relied heavily on word of mouth and newsletters to get the word out. With the hiring of full time and seasonal staff in the mid-2000s, we were able to serve more visitors through expanded collecting days and through improved marketing.

Recent trends

From 2011 to 2015, we experienced some ups and downs. In 2012 and 2013, Penn Dixie offered new — and greater numbers of — programs and group tours. However, poor weather conditions hurt our general attendance in 2014 and 2015.

You’ll see that we are busiest in July and August, since these are the months when school is out and people are traveling. Our summer visitors are comprised of a mix of local collectors and fossil enthusiasts from around the country and the world. In 2016, for instance, we’ve welcomed visitors from 35 states and five countries. Our visitors represent a breadth of experience levels: some are world-renowned fossil collectors, some are science fans who collect rocks and minerals for fun, and some are first-time collectors.

To attract out of town visitors, Penn Dixie relies heavily on internet searches, communications within amateur and professional paleontology communities, brochures in places like the Hamburg Chamber of Commerce, and word of mouth. We’re pleased to have such a good reputation in the fossil collecting community — based on decades of hard work from our staff and volunteers — and will work diligently to keep up our reputation at the top fossil part in the U.S.

We shifted our marketing

Regional visitors are drawn to Penn Dixie through advertising, word of mouth, and community engagement (e.g., our booths at the Erie County Fair and Hamburg Burgerfest). In the past, these efforts involved many volunteer and staff hours staffing festivals and other events. This year, we refocused our marketing in the region to reach new audiences who might not had previously heard of Penn Dixie. These were some of our initiatives:

  1. A new website. We redesigned our site to be more user friendly and to include as much information about the first-time visitor experience as possible. We wanted our new guests to understand what this fossil collecting business was all about!
  2. Enhanced social media presence. We put our Facebook page on the fast track (see chart below) and it boosted traffic to our website and our physical site. We also created a Twitter account and started blogging — how meta that you’re reading this!
  3. We included discount coupons in local newspapers and magazines and in the Hamburg Visitor’s Guide. The Hamburg Chamber of Commerce is awesome, btw.
  4. We distributed coupons to participants in our group programs with the hopes that they would bring new visitors to our site.
  5. We shifted some of our advertising from traditional media (e.g., newspapers and magazines) to online media (e.g., Facebook and Google Ads).
  6. We reduced our quantity of community events while increasing the impact of our presence at the events that we did attend. For example, we decided against traveling to the Syracuse Gem & Mineral Show but did attend a children’s fair at SUNY Buffalo.
Our Facebook likes more than doubled over the past year. Facebook is the #2 referrer to our website; Google is #1.

Lucky us

We were fortunate that this combination of changes was successful. As luck would have it, we were also in the right place at the right time. We didn’t know it then, but some visitors from India went back home and decided to open their own fossil park and model it after Penn Dixie. The Buffalo News and Artvoice did an excellent job describing this new partnership. We benefited from a lot of great press this year, and you can see all of the articles on our media page.

Similarly, we were excited to host our largest ever Dig with the Experts this spring. Channel 4 News did a live feed from our site the morning before the dig, and our website experienced a surge of visitors as a result. And, as a result, we had even more visitors attend the dig, more new fossil collectors come to the site during the summer, more birthday party bookings, and welcomed many new members to our society. It’s certainly a funny feeling to have a 3rd grader come to the site and say “Hey, I saw you on TV!”

Our luck continued and our high visibility encouraged new advertisers to reach out to us. In a very short period of time, Penn Dixie was approached by Groupon — a nationally recognized leader, Seize the Deal/Townsquare Media — with radio advertising (!), and Entertainment — printers of the famous books — to do promotional deals. Of course we said ‘YES!’ And, each of these deals helped us to further boost our admissions.

The next steps

So, where are we headed? Despite this huge increase, we’re NOT swimming in gold like Uncle Scrooge (below). Sadly, our revenue doesn’t double along with our attendance — though if it did, I’d be writing this from a much more comfortable office chair! Much of our admissions revenue goes towards labor costs, which include staff salaries, payroll taxes, and employee-related expenses such as disability insurance. It’s not very exciting, but that’s the reality of a small nonprofit. For example, just as a great deal of my time is spent away from the fun stuff going on at the site, much of our revenue goes to unexciting things like insurance, bookkeeping/accounting, and other operating expenses. If any insurance or accounting people reading this, I’m sorry! 

The good news is that increased attendance allows us to make a stronger case for grants and public funding. More visitors means that more people know and appreciate Penn Dixie, which translates to better chances for us to grow in the future. Plus, if we’re careful about how we commit our staff — and blessed with help from volunteers — we can use some of the proceeds from increased admissions to invest in the future. These funds might go towards the hiring of additional staff — which helps us to offer new programs — and advertising. And, I know that I’d love to work out of a building on the site — which would allow us to remain open year round — and showing increased attendance is perhaps the best way to justify that expense.

One last thought

On a personal note, I love seeing first-time collectors at the site, especially families with young children. We provide an incredible and unique opportunity for science learning at a very affordable cost. Plus, we’re in an outdoors setting, which means that visitors need to tune out their electronic devices to get the full experience. Despite having collected fossils for over two decades, I’m still thrilled every time I find something new — which is very often at Penn Dixie as you probably know — and am encouraged when our guests experience that same feeling.
