I have a new paper out in Environmental Biology of Fishes on the effects of parasites on the life history of White Sands Pupfish! The two main findings being: 🧵(1/3) rdcu.be/eptDZ

Please enjoy this ridiculously cute butterfly, which was about the size of my pinkie fingernail. It's in the butterfly family called metalmarks (Riodinidae). Males, like these, have reduced front legs and perch using only the rear 4 (females can use all 6). Sarota acantus; Costa Rica 🐙🌿 #insects

Everything is on fire but we have an awesome new lab logo from @nepeteaa.bsky.social who you should definitely have make one for your organization!

Nothing like a visit to the dentist costing more than double what I expected. 😭 Commissions and, if you’re feeling generous, donations would be hugely appreciated right now. Get in touch if you want me to draw some dinosaurs or other creatures for you!

"gentle giants"? I don't think so. Get smushed, theropod. Acrocanthosaurus vs "Astrodon"

We take tariffs on our beautiful Heard Island very seriously. We will be consulting all mammals and flightless birds and will make an announcement in the near future detailing our response. #heardisland #tariff #mcdonaldisland #trumptariff

Can someone please explain why journalists have stopped pointing out that the executive branch has no constitutional authority to end these programs?

My 25 years of palaeoart chronology... 2022 Korean translation of Locked in Time (by @deanrlomax.bsky.social) commissioned me to colourise my 50 greyscale illustrations. Here's "The Transient Oasis," showing a colony of #Crinoids drifting on deadwood. #SciArt #PaleoArt #Ichthyosaurs #JurassicWorld

New Plioplatecarpus peckensis skeletal mount 🤩🤩🤩 love to see Bearpaw mosasaurs and ESPECIALLY plioplatecarpines getting the limelight. I’m super lucky to have consulted a bit for this and some other upcoming mounts… Stop by the MOR the first week of July for the rest!

This isn't the first time a branch of government has attempted to control Smithsonian exhibit content. In 1994, a draft script for a National Air and Space Museum exhibit featuring the Enola Gay (the plane that dropped two atomic bombs on Japan) was circulated among interested parties. 🧵

how come in Japan you can get cool figures of every weird animal ever for literally ~ 2 USD, why can't we be a proper country and have Shrimp Figures

This is it folks, time to see the face of my thesis defense…

Great news. Nay, the best news. Flickr user and all-around hero grafxmangrafxman has uploaded photos of every single fossil and text graphic from the old NMNH fossil halls. Including many that I had failed to document. I'm ecstatic! Thanks Enzo B for the heads up. www.flickr.com/photos/80431...

Painting from early 2020 - I think i finally started figuring out oil paints at that point Oils on wood - can't remember the size, I don't have it anymore

Today’s random piece of nostalgic palaeoart: Brian Franczak’s Stygimoloch! This painting was one of the very first Stygimoloch reconstructions I ever saw and totally framed the way I imagine this animal. The colour choices are lovely, both for the animals and the environment. (1/4)

The absolute mismanagement and negligence of the dangers that could be caused from these actions should 100% satisfy the terms for submitting a request for Trump’s impeachment. The recent crash was entirely preventable and I hope Congress does not let this slide by. www.huffpost.com/entry/trump-...

I've deactivated my Twitter after weeks of trying to save as much of the data as possible, unfortunately Bookmarks don't export with your account data but other than that everything is saved. Daily nostalgic palaeoart will resume eventually, if I can find the time. (Art by Matthew Kalmenoff)

The osteology of derived tapejarids is quite weird when compared to other azhdarchoids. All the limb bones in Tapejara, Tupandactylus, and Caiuajara are really lightly built and slender, even compared to the closely related Sinopterus. I wonder why...

hello late #PortfolioDay !! I'm Avi! Full time artist, doing direction (and many other things) in animation, and paleoart in my free time. I'd be happy to work on scientific illustrations and reconstructions! I do both extant and extinct animals and i'm open for some work rn :) #sciart #paleoart

Devonion fishies Elpistostege (close relative of the famous Tiktaalik) and couple of bothriolepis swimming by. Needs updating but still thinking this is one of my better paintings I have done

I thinks it's time to resurrect #TrilobiteTuesday, don't you? To get things rolling with a #sciart twist, here's my favourite T-shirt featuring the wonderful work of christinekoch.com

Hope I'm not late for #TrilobiteTuesday A couple of them do appear in my next project 👀, like this Cambrian Palaeolenus
