Welcome Ammonitritor scientacivium, a new Early Triassic omphalosaurid from Svalbard! 🤩 The new skull confirms omphalosaurids were a group of specialised pelagic ichthyosauriforms that likely fed on ammonoids. New paper is out now in Biological Reviews! onlinelibrary.wiley.com/doi/…
Fossilised skull, skull reconstruction and life restoration of the new omphalosaurid Ammonitritor scientacivium.

Welcoming a new UK iguanodontian, Paludohadros proudlovii, to the Wealden bestiary, a project led by Ricardo Sacamoto, Susie Maidment & @valdosaurus, based on material collected by @NHM_London >20 years ago. Lovely reconstruction from Guilherme Gehr. Paper in @JournalSystPal

50 years after the publication of The Selfish Gene, it's time for books that capture the complexity of life to take centre stage go.nature.com/4dXkdlX

The Selfish Gene, 50 years on — it’s time for an update

Nature - A focus on the gene alone has become outdated. Books that capture the complexity of life deserve centre stage.

Evolutionary 'game-changer': weird armoured amphibian lived in ancient seas

Nature - The creature’s armour cladding probably enabled it to tolerate the salty seas of the Late Triassic.

Our new paper is out! I’m happy to share that our latest research on giant salamanders has been published in Journal of Anatomy! In this study, we investigated how hybrids between native Japanese giant salamanders and introduced Chinese giant salamanders capture their prey. Using high-speed cameras, we found that these hybrids retain a fascinating feeding mechanism called suction feeding—they rapidly open their mouths and suck in water along with their prey! The video below was recorded during our experiments with giant salamanders housed in my laboratory. Check out our paper here: doi.org/10.1111/joa.70262 #GiantSalamander #Herpetology #JournalOfAnatomy

Suction‐feeding performance in invasive alien giant salamanders within the functional framework of...

Using high-speed video, we quantify suction-feeding variability in hybrids of Andrias japonicus × A. cf. davidianus. Body condition and attack geometry modulate prey kinematics, revealing a flexible...

Ammonitritor, a new member of the Omphalosauridae family that lived in Svalbard 250 million years ago—shortly after the Permian-Triassic extinction—possessed a rather peculiar set of teeth, which it is believed to have used to crush cephalopods.

As dinosaurs evolved into birds, their ear canals changed shape, which was thought to be an adaptation for flight. A study finds that the avian inner ear may have instead been shaped by the reorientation of the skull–neck joint. In PNAS: ow.ly/blWS50ZZomg

Jeżeli połączymy wypowiedzi prof. Mróz-Gorgoń o 20 latach cięzkiej pracy naukowej z wizjami Ministry Zioło-Pużuk i informacjami o 150 mln wydanych na MDPI to konkluzja jest oczywista: nie ma dla polskiej nauki ratunku, trzeba zachęcać młodych do wyjazdu żeby się nie zmarnowali.
