Rudists: Extreme climate witnesses

Rudists, extinct bivalves with massive shells, built vast reefs in the tropical Cretaceous seas. Clumped-isotope analyses of well-preserved shells from Oman, were used to reconstruct seawater temperatures from 75 million years ago.

Crinoids with unusual morphology

In the prestigious series Treatise on Invertebrate Paleontology, a chapter was released that synthesizes data on the functional morphology and paleoecology of crinoids with unusual morphologies. It illustrates how, over more than 485 million years, they repeatedly deviated from their original body plan: from benthic forms to pelagic species.

The direct ancestor of cowries

A taxonomic revision of the extinct genus Zittelia from Jurassic sediments made it possible to trace a gradual evolutionary change in shell morphology: from the earliest species with an oval shell and elevated spire to later ones with a more globular form,
