New paper led by my graduate student @crowleyk.bsky.social investigating the evolutionary origin, phylogeny, and biogeography of flexible crinoids across the Late Ordovician Mass Extinction! Huge congrats to Kiera on her first 1st authored paper. Check it out!
On the origin and evolution of Superorder Flexibilia (Echinodermata): a Bayesian tip‐dated phylogenetic assessment of Ordovician–Silurian flexible crinoids
The crinoid Superorder Flexibilia originated in the late Middle Ordovician and, following the Late Ordovician mass extinction (LOME), radiated into one of the major constituents of Palaeozoic crinoid...
