FYI #AncientSky - the upcoming release of Caitlin C. Gillespie's "Women and Resistance in the "Annals" of Tacitus" is happening soon. And, it can be on your bookshelf, if you do not resist your excitement and head to the @cornellupress.bsky.social site: www.cornellpress.cornell.edu/book/9781501...

This is fantastic! Congratulations!

Honored that #NearLab work on fish phylogenetics is recognized with this award, in particular our work on Black Basses (Micropterus) that includes the famous Largemouth Bass

Acanthomorph teleosts (spiny-rayed fishes) comprise nearly one third of all living species of vertebrates. This important study describes a new fossil taxa that pushes the group back 20 million years in the geologic record!

The non-cryptic, cryptic species! Love it!

Cryptic species are widespread across vertebrates Abstract. Many species delimited by morphological data contain two or more species that are distinct based on molecular data (i.e. cryptic species). Crypti

A very interesting and well-executed study.

What were the first animals? The fierce sponge–jelly battle that just won’t end For almost two decades, scientists have debated whether sponges or comb jellies are the first animal lineage. Now some are calling for a more harmonious approach.

From 1,750–2,000 m deep, we collected one of the rarest deepsea fishes out there: a one-jaw eel (family Monognathidae). Only ~100 specimens of this group are known worldwide and we hold the largest collection (~46), most just a few inches long… The one we collected though, 6 inches or 154 mm!

There are 8 million fish in a World War II bunker outside New Orleans. More arrive soon. Hidden in a World War II bunker near New Orleans, Tulane stores more than 8 million preserved fish — and the collection is still growing.

Multifaceted impacts of an innovation on dental diversity in an adaptive radiation of cichlid fishes Abstract. Evolutionary innovations bring species into new ecological zones by opening ecological opportunity. However, innovations can have varied effects

New paper out now! We show that innovations can have varied effects on a phenotypic evolution, determined by the interaction between external ecological context and internal changes to organismal structure. Read here: royalsocietypublishing.org/rspb/article...

Adaptive radiation of pelagiarian fishes at the K/Pg boundary led to rapid diversification of mandible morphology Abstract. Mandibles represent a key evolutionary innovation that has enabled jawed vertebrates to adapt and diversify in response to a range of food source

New paper! Here we look at shape evolution of the mandible in Pelagiaria, a group of open-ocean fishes that includes tuna and mackerel. We find that shape disparity accumulated rapidly at the origin of the clade at around the K/Pg boundary... academic.oup.com/evlett/advan...
