I'm not an expert in egg-snatching, but I've done a fair bit of investigating into the subject, and I'll say right now, most egg-eaters consume their food in situ (that is, in the nest). They don't take it somewhere else. Egg-carrying is highly inefficient, and adaptations for it are questionable.

Spent #FossilFriday tweaking my Anchiornis colour reconstruction. The black+white+red intepretation does entirely match the melanosome data recorded for this species, as there's evidence of phaeomelanin (= rufous hues) on the arm, and lots of grey across the body. #paleoart #sciart #paleontology

If you’re wondering why your friends in academia are a little on edge right now, it’s because an eighteen-year-old who hasn’t done the reading, doesn’t look at the assignment, and has does no critical thinking skills more complex than “because I think it’s in the Bible” can literally end your career

it appears plagiorizer William Toosey tries his shit again, that's my Propalorchestes in his "Journey through the Cenozoic".
I suspect this is just the tip of it. Many of these are just other people's work with a new texture slapped on top.
Lots of JRC art here.

This is really gross: a book full of plagiarised #paleoart published by a legit UK publisher. As if we don't have enough problems with AI! There is no excuse for the author/artist not knowing better, either: this isn't the first time they've been caught committing major acts of plagiarism.

Diversification dynamics and age-dependent extinction in neoselachians over the past 145 million years.
Diversification dynamics and age-dependent extinction in neoselachians over the past 145 million years.
New paper alert!
We reconstructed the diversification trajectory of sharks & rays over the past 145 myrs to answer:
When did they experience major extinction events?
Does age play a role in extinction selectivity?
If so, does it change with extinction intensity?
