A "remarkable" three-eyed predator nicknamed the "sea-moth" that lived 506 million years ago has been identified.

A "remarkable" three-eyed predator nicknamed the "sea-moth" that lived 506 million years ago has been identified. The fossilized remains of the unusual creature, called Mosura fentoni, were ...

Abstract Euarthropods are an extremely diverse phylum in the modern, and have been since their origination in the early Palaeozoic. They grow through moulting the exoskeleton (ecdysis) facilitated by ...

In a recent paper published in National Science Review, an international team of scientists reveal how the first apex predators grew. Amplectobelua symbrachiata, an ocean-dwelling relative of ...

Four families within Radiodonta have been established. The raptorial predator families Anomalocarididae and Amplectobeluidae were dominant early in the evolutionary history of Radiodonta, but were ...

Dinocaridida, which include opabiniids and radiodonta, were abundant after the Cambrian explosion; these creatures scuttled through an ocean-dominated Earth around 500 million years ago. They looked a ...

"Besides their ecological importance, Radiodonta have a very bizarre morphology that has puzzled scientists for over a century since their first fossil discoveries in [the] 1880s." Radiodonts are ...

A bizarre fossil from China's Chengjiang Lagerstätte site hints at early diversity in a group of Cambrian marine arthropods called radiodonts.

This character combination is unique for the Chengjiang biota. A circular ventral mouth is seen in Radiodonta and in some of the gilled lobopodians which are thought to be among the radiodont’s ...
