1/13 🚨🚨 I am so excited to present our new paper, six years in the making. Here, we provide the first strong evidence that there is a molecular mechanism behind the origins of living fossil lineages! #biology #science #paleontology academic.oup.com/evolut/advance…

Whoever is now running this account has never ever touched a scientific journal in their life. I am willing to put money that. Fascists.

🧵IT'S OUT! I'm thrilled to share my study study on the dinosaurs of the Merchantville Formation, including the description of baby hadrosaurids and the return of the Dryptosauridae-the eastern US's own tyrannosaur family... #science #paleontology #biology #dinosaurs

Because anyone who thinks mining the deep sea is (1) a good idea economically (it isn't) and (2) won't contribute to absolutely trashing a totally deregulated ecosystem that is key for fisheries is an idiot.

The reputation of dinosaur paleontology being in tatters due to a bunch of ego-driven men should be unsurprising to anyone who has looked at history, because that's been the case since forever!

1/10 ⏰⏰ The final version of our #anglerfish #evolution paper is out @CurrentBiology ! In it, we demonstrate how this clade rapidly assembled a unique trait-sexual parasitism-and secondarily invaded the open ocean in a manner reminiscent of whales! doi.org/10.1016/j.cub.…

🚨🚨 1/8 New paper from @TJNear, Alex Dornburg, and myself! We reconstruct the early evolution of acanthopterygian fishes, which include ~1/3 of living vertebrate species! biorxiv.org/content/10.110…

1/7 ⚠️⚠️NEW PAPER! Excited to present my new paper-not one, but TWO new choristoderes-big amphibious reptiles-from the Paleogene of the US housed in @yalepeabody ! #science #paleontology bmcecolevol.biomedcentral.com/articles/10.11…

🚨🚨 1/8 Very pleased to share a new preprint with @TJNear and @Euphanerops! Here, we uncover the evolutionary history of one of the most iconic groups of deep-sea vertebrates: the Holocephali. biorxiv.org/content/10.110…

7/13 By calculating rates of substitutions per site across a set of >1000 exon sequences in 481 species, we found a possible answer: gars have the slowest rates of molecular evolution in jawed vertebrates.

4/13 We had noticed that in contradiction to essentially all other species, the two living genera of gars still hybridize despite diverging in 105 million years ago. These hybrids are near perfect intermediates b/w parental phenotypes!
