Whiteside Emblem 125


Stay in the Know

If you couldn't tell I'm just cuckoo for Dimetrodons and Edaphosaurs and Eryops'es and Diadectes'es and Lysorophus'es and Seymourias and Captorhinus'es and Secodontosaurus'es and Varanosaurus'es...


Our newest dig site has a really great Dimetrodon, and that has us very excited because of the odd preservation and deposition. We are typically used to floodplain sediments, but this guy, nicknamed George, was preserved in conglomerates, which is essentially cemented gravel. Highly unusual for our area. Plus, the conglomerates seem to be Pennsylvanian limestone as well which dates back thirty or more million years, so double-weirdness.
