Our #mormyrid paper is finally out in Eco&Evo!๐ We show that trophic ecology of African elephant fishes differs within the species community, incl. three species (two undescribed!:-) of the Mormyrus genus from the Sanaga River in Cameroon. Thks, Gina!

Let's support James as he presents his research on evolutionary insights into early acanthomorphs!

New paper alert (open access)! Thanks to a new tip-dated phylogeny of bonytongue fishes (Osteoglossomorpha) with a large sample of fossils, we find that today's freshwater arapaimas and arowanas were ancestrally marine! (1/n) royalsocietypublishing.org/dโฆ
We show that the exclusion of fossils drastically changes our conclusions! Without fossils, we would infer a western Gondwanan origin and a continental vicariance process for the biogeographic history of arowanas and arapaimas! (5/n)
This paper is the evolution of the last chapter of my PhD thesis, and it took several research years, from morphological data collection to many rounds of analyses and writing. I am deeply grateful to my coauthor and former advisor @Friedman_Lab for helping and guiding me! (6/6)
Finished the parrotfish skull, pretty on the inside and outside. These guys are basically just wrasses that dialed their bones up to 10 so that they can crunch hard stuff... I respect it #backdatwrasseup
If you're at #Evol2024#evolution2024 and you're interested in morphological phylogenetics, please join me this afternoon when I'll be presenting on a new way to model among-character rate variation in morphological datasets for Bayesian phylogenetics!

Welcome to the world, Macroprosopon! Huge thanks go out to @acapomorphic and @Friedman_Lab for giving me the opportunity to work on both the skeletal and life reconstructions of this crazy fish.
Say hello to Macroprosopon hiltoni, "[Eric J.] Hilton's long face". This long-snouted fossil bonytongue was a relative of today's freshwater arapaima, but it lived in Moroccan seas 50 million years ago! Magnificent artwork by Sky Jung @HBivittatus Link: academic.oup.com/zoolinnean/โฆ
