EngagementModerate engagement

While some posts delve into technical aspects like the classification of Ptychodus, engagement varies.

ImpactHigh impact

There is a consensus that the findings have significant implications for understanding Cretaceous ecosystems.

Abstract in brief

A recent discovery of well-preserved shark fossils in Mexico offers new insights into the anatomy and classification of a mysterious extinct group known as ptychodontids, which lived during the Late Cretaceous period.
These fossils, including complete specimens rather than just teeth, indicate that ptychodontids were agile, fast-moving sharks that specialized in eating hard-shelled prey, such as ammonites and sea turtles, rather than bottom-dwelling invertebrates.
The research suggests that ptychodontids were an important part of Cretaceous marine ecosystems and their decline likely resulted from competition with newly evolved predatory mosasaurs before the mass extinction event at the end of the Cretaceous.

I will be discussing this more in an upcoming publication. In the meantime, you can read the current paper about Ptychodus here and draw your own conclusions. https://t.co/ERlaZZnVo6

If you are a fan of #ammonites, you may not want to know that a deduction from well-preserved shark fossils is that the Cretaceous elasmobranch Ptychodus may have fed predominantly on free-swimming hard-shelled prey items such as ammonites & sea turtles https://t.co/yyytCpsBrH https://t.co/cVv0M8o8FM

@darius_nau @NioCriste @CetologyH @denistyrant @Dean_R_Lomax Do you have access ? Ptychodus was a fast swimming lamniform after all, a quick look at the preserved specimen reminds me of the fin outline of Cretalamna and the spine proportion looks like IRSNB9893 to me. What do you think ?https://t.co/RRnUMLa37H https://t.co/2UUnPYXWId
