My cartoon for this week’s @newscientist.com

Caption: The Tardigrade can survive the heat of a volcano and the vacuum of space, but it prefers an open fire, a good book and a chilled Sancerre.

Image: A tardigrade (a cute, plump micro-animal with eight legs - six of which are in view) sits in a tiny armchair, reading with a glass of wine in one hand and a smile on its face.

MASSIVELY excited to see Tityus achilles, South America's first #venom spraying #scorpion, finally described in @zoojlinnsoc.bsky.social ! This new species from #Colombia can spray venom at potential predators, a striking case of convergent #evolution 🧵 (1/n) academic.oup.com/zoolinnean/a...

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).

We always encourage diverse perspectives in our research group and aim to cater to a broad audience, but sometimes lab meetings are not for the faint of heart 😂

QRP with your sketch vs final #art! #arttrain #sciart One of my rare legible sketches, the two fossil tardigrades trapped in amber: Beorn & Aerobius

line drawing of two tardigrades with lots of scribbled text around them, discussing the anatomy of the animal and the shapes of their hook-like claws

a scene split in two. the left half shows orange sap oozing from a tree, the right half shows a close up of the two tardigrades trapped in the sap, one larger while the other is half the size and more stout.

Lets share some science! @harvardoeb.bsky.social Marc Mapalo uses limb patterning genes to understand the evolution of tardigrade legs... turns out tardigrade legs have a predominant distal identity relative to those of arthropods & onychophorans 🤯 evodevojournal.biomedcentral.com/articles/10....

At long last, the Lab for Invertebrate Paleobiology and Evolution @harvardoeb.bsky.social is getting on the bandwagon! Thanks for the early adopter followers making the transition easier 😁 Will soon resume posting news about our crew and research, stay tuned! ortega-hernandezlab.oeb.harvard.edu
