Half a billion years ago, the first true eye emerged in Earth’s oceans. Fossils now reveal what that ancient crystal vision could actually see.

F or the first time, chitin has been identified in a Cambrian Period trilobite. The unexpected discovery could be useful for ...

Fig. 4: Cambrian and Ordovician trilobite body size (A) and their correlation to the inferred oxygen levels (B) and temperature (C). (B) Ocean redox conditions and widespread anoxic intervals, showing ...

A discovery made over half a century ago in Antelope Springs, Utah, continues to raise eyebrows in the scientific community. In 1968, amateur fossil hunter William J. Meister claimed to have found ...

The early Ordovician conglomerates of the lower St. Lawrence valley yield numerous fossiliferous boulders carrying Lower, Middle and Upper Cambrian faunas. In this paper the Lower Cambrian trilobites, ...

Paleontologists have revealed a "remarkable" prehistoric creature that has been "spectacularly preserved" by fool's gold—a common name for a substance called iron pyrite. The newly identified species, ...

You probably don’t think twice when you queue up at the grocery store or join a conga line at a wedding. But this type of single-file organization is a sophisticated form of collective social behavior ...

A collection of fossils unearthed in the High Atlas mountains of central Morocco have been described by researchers as some of the best-preserved trilobites ever found. The specimens owe their ...

Thanks to being rapidly entombed in volcanic ash – in a “Pompeii-like” process – Cambrian-age trilobites’ anatomy is more discernable than ever, via exquisitely preserved fossils. The fossils ...
