Serious question: anyone else get super hung up on typos in published books? Like I see a typo and realize I've been staring at it for several minutes and it's difficult to get back to reading after

two things Pieter Folkens doesn't believe in: anthropogenic climate change and shadows on countershaded dolphins. Here's evidence of one existing, which should tell you exactly how much his opinion on the other should matter

@NearlyExperts @Formorphology Probably not unreasonable to assume that they did - here's one of my favorite depictions of the K/Pg impact by my favorite paleoartist, Doug Henderson:

@Synapsida hmm yes

#SharkAwarenessDay Contrary to semi-popular belief, the giant shark Carcharocles megalodon is dead and gone, and we know it's been extinct for about 3.6 million years or so. Read more about it here: https://t.co/81n0gZWvD3

@WCBD

For #fossilfriday I naturally need to highlight our new paper on Ankylorhiza. Ankylorhiza means "fused roots" - most early diverging dolphins have double rooted teeth, but nearly all the teeth are single rooted - making it one of the first dolphins to evolve this condition.

#fossilfriday Some of my paleoart (Parapontoporia, Psephophorus, Balaenoptera bertae, Pelagiarctos) and a few recommendations - emphasis on those who also do marine critters! @BranArtworks @JoschuaKnuppe @BrianEngh_Art @HodariNundu @AlexBoersma_Art @paleofan @bone_sharpe

@Extinct_AnimaIs Unless the scuba diver is a 3 year old, this pinniped as drawn is like 20 feet long. We found that Pelagiarctos was no more of a 'killer walrus' than many modern sea lions , and it probably ate mostly fish. Artwork below by me. Read more here: https://t.co/k6Qjf8RFUk
