New Paper by Parry et al., reinterpreting the oldest diverse #jellyfish fauna as sessile polypoid dinomischids 🪼
These findings significantly expand the temporal and geographical range of dinomischids, elucidating their morphological and taphonomic variation.

🚨Paper alert🚨 Permian bacteria fossilized as rod-shaped pyrite aggregates! A sweet taphonomy-oriented project led by L. Melim. If pyrite aggregates can similarly form in spherical bacteria, how could we distinguish them from extracellularly formed framboids 🤔🤔🤔

#FossilFriday Elrathia kingi is one of the most common trilobites in the Cambrian rocks of Utah’s West Desert. Thousands are found yearly—many geologists have one on their fridge. Yet this specimen - first published in 2008 - is the only one I know of that preserves both limbs and gut remains. 🤩

Many may not remember the DENDROGRAMMA mystery! This weird mushroom-shaped thing was described in 2014 as a "new metazoan" of unknown affinities! They were hinting that it might be a new phylum-but THEN 2 years later @drtimohara.bsky.social sequenced it and BOING! BENTHIC

Scientists first collected a pig butt worm from the dark ocean depths near Monterey, California. The size of marbles, pigbutts are a near complete mystery. Officially described in 2007, scientists aren’t even sure if the pigbutt form is an adult, or just a very very awkward adolescent stage.

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:

Gills of lamprey ammocoete larvae, cephalochordates & the hemichordate enteropneust Saccoglossus are not for gas exchange. Instead, they function in ion regulation! Enteropneusts (="gut breathing") do not breathe from the gut.
