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/…
ALT Fossilised skull, skull reconstruction and life restoration of the new omphalosaurid Ammonitritor scientacivium.

A newly identified fossil amphibian, measuring 737 millimetres in length and dating back around 237 million years, may have been fully adapted to life in the sea, according to a study in Nature Ecology & Evolution. go.nature.com/4iiWdep

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

NEW AMPHIBIAN - G. maritimus
A new species of Gerrothorax has been described from Late Triassic China based on two nearly complete skeletons showing this species was adapted to marine habitats!

Importance of paleo perspective on biogeography, cool paper!: The present does not reflect the past: geographic mismatches between fossil and modern records are widespread across the tree of life royalsocietypublishing.org/r… @ErinSaupe

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:

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.
