Our new paper on a tiny Wealden 🐊 is now out, with @tetzoo.bsky.social, @neilgostling.bsky.social and co. As a critical taxon close to the origins of the living croc lineage, we used microCT to build a comprehensive morpholgical atlas to reassess its evolutionary relationships. tinyurl.com/4t592crr

Anyone have a PDF of
"Price, L. I. (1955). "Novos crocodilídeos dos arenitos da Série Bauru. Cretáceo do Estado de Minas Gerais". Anais da Academia Brasileira de Ciências. 27: 487–498"?

I've been looking for it and I've yet to find anything on it other than more recent studies citing the paper

A young Eogavialis basks on the shoreline. While he doesn't care about anything except for fish, most other animals aren't going to chance his toothy grin.

They are also generated by some
squamates and nonavian theropod dinosaurs, but the for
mer were too small and the latter insufficiently alive to
have left these marks at Hadar

New crocodile species described by Brochu et al and man I just love these little cheeky comments thrown in here and there.
This particular section discusses the presence of a certain type of bite marks on the fossils.

A photograph of the fossil remains of Galahadosuchus, both in its natural state and with the bones highlighted. The image shows that we have most of the right hindleg, the femur of the left and a series of tail vertebrae just behind the hips

A multiview 3D reconstruction of Galahadosuchus by Matt Dempsey. It is depicted as a gracile, long-limbed animal taking on a digitigrade posture with a narrow triangular skull and a long tail.

We got our first "croc" of the year, Galahadosuchus from the Late Triassic UK. A gracile saltoposuchid known from the hindlimbs, a chunk of the tail and assorted other isolated postcrania. And with a live reconstruction by no other than Matt Dempsey

The #DinoConUK statement is really making the rounds because prior to yesterday I'd have never imagined it would get covered by Internet Today
Tho I wish it would have been under happier circumstances

I'd compare it more to the Indoraptor but yeah I see what you mean, I mean it is ILM so I guess that design philosophy does check out?

2 months ago 2 0 1 0

Given the varying quality of the models its hard to say how much of this is a legitimate design choice and how much is just mistakes
overall they strike me more like rauisuchians, but honestly the dinosaurs in the scene look a bit derived for the triassic at first glance

Interesting moment where the trailer seems to feature what looks to be a pair of pseudosuchians? tho I can't quite put my finger on what type specifically

given the theropods something more late Cretaceous seems plausible, so perhaps they are meant to be baurusuchids?

The fossil of DMA-JP-2009/001 as it is preserved. The skeleton is complete and posed in a U-shape, with the head curving up to the right and the tail to the left. A scalebar is shown equivalent to 1 meter.

New paper just dropped finally describing a complete specimen of Dakosaurus maximus and what a beauty it is. Some highlights, in addition to this being a long time coming, is the presence of bitemarks on the face and chondrichthyan material in the stomach

Paleoart of a Numidotherium family by the beach. The animals are shown as squat, hariless animals with a strange bulbous forehead and short trunk for a nose. In the foreground a small early creodont runs past the family as one of the Numidotherium rests on a branch. A juvenile walks up to the resting individual while a third looks straight at the viewer.

What we do know with certainty tho is that Eremosuchus comes from the same deposits as Numidotherium, a bizarre early elephant-relative, illustrated here by Joschua Knüppe

It might be a biogeographic link between South American and European forms, it might be an offshoot of the latter or well who knows, sebecid phylogenies are a mess that requires a lot more material to decipher

Accordingly, do take the size comparison with a good pinch of salt as we know next to nothing about the animals proportions, we don't even have a complete lower jaw and frankly we barely know how it relates to other sebecids either.

Eremosuchus is pretty cool since its the only named sebecid from Africa (and one of the few African sebecids period alongside the Fayum Form from Egypt), but sadly only known from a handfull of fragmentary bones including two dentaries of an adult and a presumed juvenile
