Dunkleosteus - Smaller and Rounder Than Expected?

Dunkleosteus is among the most well-known of prehistoric fish, and prehistoric life in general, and are the prime representative for the class of fish known as placoderms, and of the clade Arthrodira, of which they are the largest known member. This diverse group of animals ranged from Dunkleosteus of course, representing giant apex predators, but also detritus-nibbling bottom dwellers, which ranged in size a good amount. The size of Dunkleosteus though, and their proportions have however been consistently unclear due to their head and thoracic armour being the only elements of their body which are regularly preserved in the fossil record, and to fill in the gaps, utilizing the remains of other more complete placoderms has been essential in trying to build a more complete picture of them and how they appeared. Now, a new paper has been published that calls into question their larger size estimates, and well, calculates much smaller sizes for them. How valid are the claims presented though? Find out that and more in this video! I hope you enjoy.
