Thrilled to begin today a new postdoc at @UChicago with @NeilShubin funded by BSD #chicagofellows ! Stay tuned for some evo-devo on the head across the fish-to-tetrapod transition

It would have never been possible without the amazing international team of exhibition, scientific committee, and the people building this stunning skeleton #prehistoricminds

If you are interested to learn more about a new, large troodontid and what this suggests for postcranial evolution among theropods, don't miss my talk on the 5th of November at 11:45 am! #2022SVP

New paper today led by Han Hu on the 3D skull of Jeholornis! In addition to the bones, we managed to get some nice insights regarding the sclerotic rings and the endocast: Jeholornis was probably diurnal and had relatively good sense of smell

this is better explained in the method section. You can also counter check the dataset with all the scorings for a better idea of how we applied the definition

For this #Easter #FossilFriday , enjoy this wonderful soft-shelled Protoceratops clutch showing awesome #dinosaur embryos

#Fossilfriday Baryonyx, a subaqueous foraging spinosaurid from UK (nature.com/articles/s41586-0…), hunting on Lepidostes. The gut contents of the holotype of Baryonyx currently housed at the @NHM_London show evidence of piscivory. artwork by @d_bonadonna

Mapping bone density into an amniote-wide phylogeny, we found that, based on our data, high bone density is ancestral for spinosaurs, indicating that #Suchomimus lost this trait secondarily. Art by @d_bonadonna

The presence of high bone density in #Spinosaurus and #Baryonyx is not limited to femora and dorsal ribs: this extends to all other appendicular elements and axial skeleton. Additionally, spinosaurids show axial pneumatization only in the cervicals, favoring a denser skeleton

We used bone density to infer underwater behavior among extinct taxa: although this is rare among dinosaurs, #Spinosaurus and #Baryonyx are predicted as subaqueous foragers, while #Suchomimus is recovered with a non-diving ecology.

Among spinosaurids, we sampled the neotype of #Spinosaurus, the holotype of #Baryonyx, and #Suchomimus

CT scan and thin sectioning were applied to collect cross sections of femoral diaphysis and proximal region of the dorsal ribs. Each cross section was then transformed in a black and white figure to quantify bone density in BoneProfiler (http://134.158.74.46/BoneProfileR/)

To test for correlations between bone density and ecology, we built a dataset of 380 femora and dorsal ribs representing 291 extinct and extant amniote species, including mammals, modern reptiles and birds, marine reptiles, 39 non-avian dinosaurs, and 7 Mesozoic stem birds

High bone density is a striking feature of aquatic animals, because it helps in buoyancy control. On the other hand, terrestrial and flying amniotes (reptiles and mammals) have a large medullary cavity in their long bones, leading to a lighter skeleton. Art by @d_bonadonna

Have you ever noticed how some modern semiaquatic animals do not show striking anatomical traits in their skeleton, such as the hippopotamus and tapirs? If these animals weren’t alive today, how easy would have been to correctly guess their ecology from their skeleton?

For this #FossilFriday enjoy the mounted skeleton of #Máximo the #titanosaur (Patagotitan) exposed at the @FieldMuseum . This is currently believed to be the largest dinosaur that ever lived! Note the Homo sapiens below its belly as a scale bar

For this #fossilfriday, enjoy this stunning specimen of Pterodactylus antiquus housed at the Field Museum of Natural History! Contrary to most other specimens from Solnhofen, this skeleton is mainly preserved in three dimensions

#fossilfriday Inspired by our latest paper, look at this awesome mummified dinosaur! The specimen preserves an articulated pelvis and tail completely covered in 3D integument. The fossil is housed at the Field Museum of Natural History

Morphometrics applied to ontogenetic series of sauropodomorphs, theropods and other archosaurs show that the sauropod skull is not the result of pedomorphosis, but predisplacement: features present in adult early sauropodomorphs are found in the embryos of sauropods

We CT scanned the skulls of the juvenile and adult individuals referred to the early sauropodomorph Anchisaurus. While the adult shows traits in common to sauropods, the juvenile resembles early saurischians, suggesting that development had a role in shaping the head of sauropods

#SVP2020 if you want to know more on how the brain shapes the skull during development and how these patterns influenced the evolution of the skull in reptiles, including #dinosaurs and #birds , check our talk! @GNavalon @phyloprog @dsmithparedes @AnjanBhullar @yalepeabody

#WorldEggDay coincides with #FossilFriday ! Although eggs of extant birds come with a calcitic, hard shell, early dinosaurs possessed flexible, soft eggs similarly to modern turtles. Here, the eggs of Protoceratops and the basal sauropodomorph Mussaurus!

A huge thank to @michaelgreshko who traveled from UK to New Haven to the Sahara desert to uncover and feature our research leading to this great story! The stunning illustrations, animations and cover of NG were made by the bests paleoartists ever @d_bonadonna @ManucciFabio !!!

Equally important was the inclusion of the soft-shelled eggs belonging to the basal long necked dinosaur Mussaurus uncovered by @PolDiego! These eggs preserve embryonic remains as well. Stay tune for awesome research by @poldiego in the near future!

This is the only known clutch of Protoceratops and was found in Ukhaa Tolgod by Mark Norell during the '90s. It preserves 12 embryonic individuals in fetal position. Check out the white-brownish halo surrounding them, the remains of the soft eggshell

In 2019, @jasmina_wiemann , Fabio Manucci, Derek Briggs and I published a paper on a hadrosaur mummy and degraded organics preserved in it. Glad to see that is one of the most read papers published in Paleontology!
