New open-access paper! A team including Dr. Darla Zelenitsky (UCalgary) describes Duonychus tsogtbaatari, a bizarre two-fingered therizinosaur from Cretaceous Mongolia. Its huge claws and reduced fingers provide new insight into theropod evolution and forelimb reduction. Exceptional fossil preservation even shows the keratin sheath on the claws!

for some reason, a #fossilFriday question has come into my head: How many complete, articulated therizinosaur necks are known?

(Suddenly I'm suspecting it's no better than the sauropod neck situation ...)

(edit: actually, I must have thought it because @punkpaleo tooting this pic of Nothronychus claws:

Attached: 1 image It's another #FossilFriday with fossils from the NHMU! Here's claws from Nothronychus, a therizinosaur that roamed the southern United States. Prior to its discovery, therizinosaurs had only been known from China and Mongolia! #paleontology #dinosaur

Important fact: All dinosaur-themed advent calenders are required to include at least one (1) Therizinosaur or Deinocheirid named Santa Claws.

Similarly, Pleistocene-themed advent calenders must include at least one giant ground sloth or giant anteater named Santa Claws.

Do not tolerate any exceptions.

Thank you.

My next art fight attack is a therizinosaur named Sirrius, who was created by Lighterium. :) The cloudy pattern was fun to draw. #MastoArt #ArtFight2022 #ArtFight #Sirrius #Therizinosaur #Dinosaur #iPadPro #Procreate
