Velvet worm repeat pattern! Putting more invertebrate linocuts into surface design! 🧪🐡 These adorable, caterpillar-like blue velvet worm from New Zealand (Aotearoa). Velvet worms (phylum: Onychophora) are named for their velvet-like texture and somewhat wormlike appearance. They are elongated, 🧵

Long day today, so one photo only. I got a face shot of Old World swallowtail or kiageha (Papilio machaon) caterpillar. Those little eyes! Short legs! Chonky body! Tokikubo, Komoro, Nagano #Invertebrate #Insects キアゲハの幼虫。お目目とお手手。長野県小諸市鴇久保 #虫

For #FossilFriday, probably my favorite specimen at @hmns.bsky.social. This horseshoe crab had a very bad day.

I see #Crustmas seems to be a thing, and people are sharing Ostracod photos!? I don't need an excuse to share photos of my Favourite crustacean! Or better yet, here's a video! #BugSky #invert #PondLife

Tis #Crustmas is the season of giving or not? 😅 I remember people were asking if they eat their moult. Yeah they do eat it and they dont seem to enjoy sharing moult snacks. 😆🦐

For #FossilFriday have you ever considered the scorpion fossil record? This is surprisingly rich, but how we categorize these animals transcends being a hot mess. It's a spicy disaster. My colleague Jason and I wrote a paper on it which came out today: peerj.com/articles/185... ⚒️🧪🦀🦑 #evosky

A project about Mary Anning fell through earlier this year, but that didn't mean I couldn't make an illustration of her, cause she was awesome. Found ichthyosaurus skeleton, plesiosaurus skeletons, loads of ammonites and fish fossils. Survived a lightning. All cool stuff! #illustration

Chances are the 🦃 on your table didn’t come with the feet still on it, so you won’t see the awesome spurs! And just for fun: here’s an #Idaho #fossil turkey foot, with spur(!) from the last interglacial period. This turkey knew some mammoths! 🦃 🦌 🦣 🦁 🐴 🐪 🦬 Happy Thanksgiving 🍽

Though only about half of the world’s rhino species have gone extinct since the late Pleistocene, to get the full story, we should take a look at how massively their distributions have shrunk. Even in historical times, Sumatran and Javan rhinoes were more fittingly southeast Asian rhinos.

Amazing fossil alert. Jurassic salamander from China. You can see the soft tissue of the eye, gills, limbs, even the folds of its tail. And its last meal its stomach… 🧪 #evolution #paleontology

Arthropleura, the largest known arthropod to ever exist at an estimated 2.5 metres long, walks slowly along an ancient Carboniferous coastline looking for food.

How do you like 𝘛𝘦𝘢𝘭𝘭𝘪𝘰𝘤𝘢𝘳𝘪𝘴 𝘸𝘰𝘰𝘥𝘸𝘢𝘳𝘥𝘪𝘪 (Etheridge, 1877) from the lower Carboniferous Glencartholm volcanic beds of East Lothian? 🦐 Whilst on first impression it looks to be a shrimp, it’s actually a member of the Peracarida and therefore more closely related to isopods than to decapods!

Baltic isopods. Did this for pollinator week last year, a study showed that this species of aquatic isopod helps certain kinds of seagrass spread, making them one of the first known underwater pollinators!

Don’t mind me hopping onto this but dark and moody #paleoart is my jam!! #SciArt #artbyjulio

Hidden Menace

This frozen "Mystery Mummy" was found in the Klondike permafrost, and is likely several tens of thousands of years old!! But what species is this? We don't know! What is your best guess? We have a sample in our lab, and are working on sequencing it's DNA, so can soon tell you who got it right 😀
