How long do crinoids live?

For the first time, the lifespan of deep-sea stalked crinoids was determined using the bomb radiocarbon method, which relies on the ¹⁴C signal produced by atmospheric nuclear weapons testing in the 1960s.

Fossil crinoids from Panthalassa

Today, stalked crinoids are confined to the deep sea, although their ancestors once dominated shallow-marine environments. Our analysis of the fossil record from the ancient Panthalassa Ocean shows that their restriction to deep-water habitats occurred much later than in the Tethyan realm.

Silica transforms through solid-state processes

We compared fossil sponge spicules up to 150 million years old with modern specimens. Using scanning electron microscopy and mineralogical analyses, we found that their silica gradually transforms from an amorphous state to quartz through solid-state processes,
