Shell Shock! Can morphometrics distinguish fossil turtle species? | PLOS Paleo Community
This is an article I wrote for the PLOS Paleontology Community blog on March 8, 2018. I am archiving it here on my personal website. View the original post here. A big component of paleontological work revolves around identifying morphological characters that diagnose distinct species in the fossil record. But therein lies an unavoidable problem: whereContinue reading "Shell Shock! Can morphometrics distinguish fossil turtle species? | PLOS Paleo Community"
