Re‐Evaluating the Thermogenic Decarbonation During Large Igneous Provinces Emplacement Using Temperature‐Dependent Thermal Properties

Abstract Large Igneous Provinces emplacement drives mass extinctions through rapid carbon release, but the relative contributions of magmatic degassing versus thermogenic decarbonation remain debated. Here, we incorporate temperature‐dependent thermal parameters into models of contact metamorphism a

Amypteride🏳️‍⚧️🔻🕷🦂

@amypteride.bsky.social

And to end today's topic, the usual drawing auto-feedback and (a lot of) refs!

Thank you for reading & I’ll see you on the next #Cheliceratime!

4/4

And to end this post, some of you may have already known this eurypterid before, and I clearly wouldn’t be surprised. Megalograptus is one of the most featured eurypterids in pop culture, as it’s been for example on of the basis of the Ark’s eurypterid, or been the first eurypterid showed in a BBC documentary from the 2000s golden age of BBC’s paleo-documentaries. Its singular look isn’t for nothing in its popularity too, as it’s one of the few eurypterids to have a morphology easily identifiable from the eurypterid’s ground body plan and deviating clearly from a scorpion-like look unlike the way more popular pterygotids.

Is this paleoart accurate ?
Apart from some tiny perspective glitches, I think that’s one of the best eurypterids I’ve ever drawn.

I had to redo the entire drawing because I missed the work on the species coloration, so apart from the orangy pattern (‘cause I wanted to give it more depth while still staying within the lines), the coloration is now supposed to match what’s supposed to have been the animal real colors.

A lot of drawings show this animal with folded second pair of legs, so I opened them a bit to give more dynamic to the animal.
