Crustaceans are well represented in fossils younger than 500 million years, but are largely absent from finds that date to the early Cambrian. But there was evidence to suggest that they should be ...

Considering the fossils of the Cambrian, the oldest fossil-bearing rocks known during his time, Charles Darwin wrote the following in the 6th edition of On the Origin of Species; … it cannot be ...

A crustacean with 3,000 lenses in its eyes, 6-foot-long shrimplike creatures and organisms that looked like tulips emerged hastily (from an evolutionary perspective) on the scene some 520 million ...

Pectocaris has a fairly basal position in the phylogenetic tree of the extant crustaceans and probably belongs to the branchiopod crustaceans. It is the first arthropod with definite crustacean ...

The anatomy of these crustaceans appears rather advanced, the scientists say, which suggests that the group as a whole likely originated during the Pre-Cambrian, a period of time that stretches ...

The oldest fossil crustaceans ever found are helping to prove that the evolutionary explosion of animals was not so explosive after all. The tiny, half-millimetre-long fossils were found in ...

Researchers announce Pac-Man ghost-shaped jellyfish is the oldest in fossil record The 505 million-year-old fossil hints at what sea life was like in the Cambrian era ...

This Cambrian period critter is now considered a part of a specific group of arthropods called the mandibulates, who went on to become some of the most successful animals on our planet in and out ...

A newly described creature from the Cambrian period is putting a bizarre twist on what we thought we knew about early animal evolution. Meet Mosura fentoni—a three-eyed, clawed, and flappy ...

New 'Dune'-like Selkirkia worm species rewrites ancient history : Short Wave 500 million years ago, the world was a very different place. During this period of time, known as the Cambrian period ...

A fossilized sea creature from 514 million years ago helped researchers solve an evolutionary mystery about one of the first animals with an exoskeleton.

A 555-million-year-old fossil found in South Australia provides crucial evidence for the Precambrian origins of Ecdysozoa, which encompasses insects, crustaceans, and nematodes. The discovery of ...
