Cockroaches are feared, hated, sprayed, and stomped. But, we can’t seem to get rid of them. They have survived multiple global disasters and even outlasted the dinosaurs, but can all of their fancy adaptations save them from the current extinction crisis? In his 2019 TEDxBuffalo talk, Penn Dixie Executive Director Dr. Phil Stokes explores why some species are more prone to extinction than others.
You may have read about our new partnership with the Centre for Himalayan Geology in the Buffalo News or Artvoice. With Penn Dixie’s support, The Centre is in the process of creating an international scientific attraction — the Kashmir Triassic Fossil Park — near the town of Khonmoh in the State of Jammu and Kashmir, India.
Many of the types of fossils found at Penn Dixie are also present in Kashmir, though the species are not the same. For instance, both fossil parks have brachiopods, bivalves (clams), ammonites, gastropods, other marine invertebrates, and various plants. However, the park in Kashmir — at least as far as we can tell — does not have trilobites, as these animals became increasing scarce towards the end of the Paleozoic Era. The Permian-Triassic extinction event — which is captured in the rocks at the park — marked the end of the trilobites’ reign on our planet.
This massive die-off — which eliminated 90% of all marine species and 70% of all terrestrial vertebrates on Earth — led to the rise of the dinosaurs. Meteor impacts, widespread volcanism, and a runaway greenhouse effect (i.e., climate change) have been proposed by scientists as explanations for the extinction event.
