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

New paper from South American colleagues: Oops, fossil jawbone from Eocene of Antarctica originally identified as a bony toothed bird is actually... just a fish. https://t.co/yAY6dYrOuC

I am five months late but thanks to quarantine, here it is: my review of 2019 in marine mammal paleontology! Abstracts, links, and some commentary. #whaleontology #paleo #paleontology #marinemammals https://t.co/k1O6NZWRLr

@AshPoust @HabitualDoodles @Yara_Haridy I can't speak for land mammals, but in odontocetes, they have tons and tons of sinuses in front of their brain to either 1) protect the brain from sounds produced for echolocation and/or 2) reduce bone conducted sounds from interfering with hearing by making "mirror" of air

#PortfolioDay I am a paleontologist and artist/scientific illustrator with an emphasis on modern/extinct marine organisms - I work in graphite, watercolor, acrylic, ink, and digital - often combining them. I can illustrate all my own scientific papers!

@OpenAcademics Actual folder names for different versions of a manuscript that was rejected four or five times over 6 years before FINALLY getting published

Chief among the new fossils from that Peru platanistoid paper is the particularly strange dolphin Ensidelphis, with this weird sinusoidal rostrum and premaxillary tusks (a bit like a waipatiid): https://t.co/I4KdGcC5wn

Another new pub, about a week late: exceptional diversity and disparity in a platanistoid-dominated dolphin fauna from the lower Miocene of Peru, including a couple of new genera! https://t.co/I4KdGcC5wn
