There's been a lull in the open conversation around abusive and creepy behavior in academic paleontology since the Me-Too era, but the problem has not, to put it mildly, gone away

A tarantula in the process of molting. That exuvia (old exoskeleton), though, is so creepy looking 😳😱😬 Freshly molted tarantulas often appear in vibrant, iridescent colors like this bright blue, which will eventually fade to more muted tones as the new exoskeleton hardens. #spiders #molting

If there were ever a “nature’s best pin-cushion mimic” contest, this pill woodlouse (Calmanesia erinaceus) would surely be among the top contenders. 📷 hollythefrog on iNaturalist 📍 Madagascar 🔗: www.inaturalist.org/observations...

‘Almost unimaginable’: these ants are different species but share a mother

Ant queens of one species clone ants of another to create hybrid workers that do their bidding.

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, 🧵

A repeat pattern made with my linocut blue S-shaped velvet worm, resembling a many-legged caterpillar with two antennas and a pattern of spots. Along its length there’s a central darker blue stripe. The image is repeated and reflected to make mesh of nearly interlocking S-shaped velvet worms against a deep raspberry purple background.

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

An image showing a range of fossil scorpions, arranged by age. These are lovely fossils, ranging from scorpions in rocks, through ones dissolved out of rocks or resolved using CT scans, to photos of more recent scorpions in Amber. If you want the full details: (A) Palaeophonus caledonicus Hunter, 1886 (Dick Institute, Kilmarnock, UK) from the mid-Silurian (Llandovery to Wenlock) of Lesmahagow, Scotland, UK, image courtesy of Lyndsay C. Jess, and by permission of East Ayrshire Council/East Ayrshire Leisure Trust, and a reconstruction from Pocock (1901). (B) mid-Silurian Eramoscorpius brucensis Waddington, Rudkin & Dunlop, 2015 from Canada. (C) Proscorpius osborni Whitfield (1885b), Yale Peabody Museum (YPM IP 545850); photo by Jessica Utrup 2019. (D) Lower Devonian Waeringoscorpio hefteri Størmer (1970, image source Poschmann et al., 2008). (E) Pulmonoscorpius kirktonensis from the Lower Carboniferous of the UK (courtesy of Andrew Jeram). (F) Compsoscorpius buthiformis from the Upper Carboniferous of the UK (left: courtesy of Lorenzo Prendini, AMNH; right: Legg et al., 2012). (G) Carboniferous taxon Cyclophthalmus senior from the Yale Peabody Museum collections (YPM IP 029827), photo by Jessica Utrup 2013. (H) Mesophonus perornatus from from the Triassic of the UK (courtesy of Lorenzo Prendini, AMNH). (I) Protoischnurus axelrodorum from the Cretaceous Crato Formation, Brazil (courtesy of Christian Neumann, Berlin). (J) Centruroides knodeli from Neogene Dominican amber (courtesy of Wilson Lourenço, Paris). (K) Tityus azari from Neogene Dominican Amber (courtesy of Wilson Lourenço, Paris).
