Darren Naish Having done a S. hepingensis, the measurements and figured caudal material suggest a reasonably short tail. A mid chevron is present, indicating that at least the mid-tail was quite thin. Not so sure about the anterior ones, but I made them longer akin to related taxa.

Honored that my team's recent research on facial expression muscles in African wild dogs was featured in Nature News! We found African wild dogs have the same well-developed 'puppy dog eye' expression muscles found in domestic dogs.

Have you seen any yet?! I’ve been doing a few exciting Swift activities this past few days. Can’t wait to see and hear them arrive in the coming days!

A river Wharfe section, pristine grayling & barbel ground GONE.
Up to 00:30 was filmed in 2019, 00:30 onwards is the seen today.
This is what my go to area for grayling is like today.
This is what we have lost and it is happening everywhere.

#AnimalFigureOfTheDay is allosauroid # 34, another metriacanthosaurid... this is the 2021 #PNSO Sinraptor, called Xinchuan. A really great model (apart from the lack of lips!), though I do wonder if the tail is too short and lightweight. #dinosaurs #theropods

Stop it with the by now generic monster theropods. Give an ornithischian a chance :B

There are few things as exciting in our little corner of science as a new specimen of Archaeopteryx...with a skull...in a major, easily accessible museum! Congratulations to Field Museum & Jingmai O'Connor! These lovely photos are from this great article: bit.ly/44w9Z64

Yikes, gotta prepare for several #AncientSeaReptiles talks in May and June - including Lyme Regis Fossil Festival - as well as The Unnatural History Museum event

I had a chance to illustrate a pretty darn cool thing! So excited to see it out. Huge thanks to the amazing crew of the Field Museum giving me this amazing opportunity.

I feel it necessary to point out that there were at least two neuroscientists on this new paper and one of the many issues in the original paper was an inappropriate statistical approach. The argument that 'fancy' statistics were not needed is incorrect.

🚨NEW PAPER🚨 Can caecilians tell the time?

Circadian rhythm and surface activity in soil-dwelling #caecilians (Amphibia: Gymnophiona) in Scientific Reports
By
Ram and colleagues

New paper! You can ID Anolis ecomorphs from just an arm! We (Kevin de Queiroz et al) compared the arm morphology of a fossil anole in amber to those of extant Anolis species. We can pretty confidently say the fossil belongs to a Trunk ecomorph lineage.

I've become a massive 'edition' nerd of my own #books . I've only just learnt that my #AncientSeaReptiles went to 2nd edition in 2023, as evidenced by publication details. A few corrections were made to the 2nd edition... lots more will be featured in the 3rd....
