One of the best & most useful scientific figures when it comes to sauropods is this one from Jannel et al. 2022. It's visually clear & gives a good idea of which sauropods we have decent hind foot aka pes material for.

My infographic terror continues to spread!
This time, prompted by nothing in particular (he lied) is the question of ontogenetic metaplastic transformation.

One of the largest temmnospondyls ever to exist: the gigantic Koolasuchus was also the last non-lissamphibian temnospondyl to exist. It survived into the Early Cretaceous of Australia when all other stereospondyls were long gone

After we published the new specimen of #Spicomellus a few weeks ago, we were contacted by George Blasing, who said he'd bought some on the commercial market, and wanted to return it to Morocco. It arrived last week. Thanks George for doing the right thing in the name of science!

#ZAVACEPHALE IS FINALLY OUT! 🥳 Our first definitive Early Cretaceous pachycephalosaur! (~15 my older than the previous oldest pachycephalosaurs) And the first hand material for the clade! I can't tell y'all how much of a pleasure it was to review this paper! ☺️

Why anatomy is hard to learn for students: text books give you definitions like this -
diaphysis = shaft between metaphyses
metaphysis = the part between the epiyphysis and diaphysis
epiphysis = the part between the articular surface and metaphysis
It's like a scientific riddle 😄

Main reason I’m in Zimbabwe is to work out if this ‘Massospondylus’ material (a selection of the tons they have) is really Massospondylus or something else. Sounds dull but has implications for dating & correlating rocks in Zim with those in South Africa & dino diversity 🦖🇿🇼🦕

Bowhead whales may not be the only species that can live to 200 years old. Researchers have found that the industrial hunting of great whales has masked the ability of these underwater giants to also live to great ages
