Crustaceans as hosts of parasites

Over the last decade, parasites in the marine fossil record have been increasingly studied. The scientific community has shown that part of the lack of knowledge about marine parasites in deep time is simply due to a lack of research.

Animals hidden in a 100-million-year-old giant clam

The sea floor was a dangerous place for particularly smaller animals. Over the last century, a wealth of information about traces in ancient prey items has been recorded, showing successful and unsuccessful predation. One of the best ways to largely avoid predators and other disturbances is to find a shelter.

‘Living Fossil’ Damselflies Get Their Own Families!

A large molecular study has confirmed what was thought for a while: some isolated groups with at most a handful of species each are so unique that they have no close living relatives remaining. Five new families were named and two were revived.

Inferring octopodoid and gastropod behavior from their Plio-Pleistocene cowrie prey (Gastropoda: Cypraeidae)

Predation is an evolutionary force shaping sea floor communities, with the record of drilling predation being particularly useful to study predatory behavior on short and long timescales. Most predatory drill holes are caused by gastropods, but octopods within Octopodoidea also produce characteristic drill holes, yet remain severely understudied in deep time.
