Study: Squids Originated and Rapidly Radiated by 100 Million Years Ago
Using an innovative digital fossil-mining approach, paleontologists analyzed more than 250 fossil beaks from 40 ancient squid species. Their results suggest that the radical shift from heavily shelled, slowly moving cephalopods to soft-bodied…

Rapid isotopic exchange in mineralogically unaltered coral skeletons
Our experiment aimed to test the hypothesis that surface texture (Fig. 1E–H), which reflects the underlying skeletal microstructure (Fig. 1I–L), is a key factor influencing water penetration and the isotopic exchange of oxygen (and other…
