Paleontologists discover 506-million-year-old predator https://phys.org/news/2025-05-paleontologists-million-year-predator.html

Early evolvability in arthropod tagmosis exemplified by a new radiodont from the #BurgessShale https://royalsocietypublishing.org/doi/10.1098/rsos.242122

"Mosura fentoni was about the size of an index finger and had 3 eyes, spiny jointed claws, a circular mouth lined with teeth and a body with swimming flaps along its sides. These traits show it to be part of an #extinct group known as the #radiodonts, which also included the famous #Anomalocaris"

Paleontologists discover 506-million-year-old predator

Paleontologists at the Manitoba Museum and Royal Ontario Museum (ROM) have discovered a remarkable new 506-million-year-old predator from the Burgess Shale of Canada. The results are announced in a paper in the journal Royal Society Open Science.

#Ordovician #opabiniid-like animals and the role of the #proboscis in #euarthropod head evolution https://www.nature.com/articles/s41467-022-34204-w

A proboscis—thought to represent a fused pair of head appendages—was not unique to #opabiniids, but instead was present in the common ancestor of #radiodonts and modern #arthropods, and through evolutionary time may have reduced to become the labrum of modern arthropods.

Welsh 'weird wonder' fossils add piece to puzzle of arthropod evolution

The most famous fossils from the Cambrian explosion of animal life over half a billion years ago are very unlike their modern counterparts. These "weird wonders," such as the five-eyed Opabinia with its distinctive frontal proboscis, and the fearsome apex predator Anomalocaris with its radial mouthparts and spiny feeding appendages, have become icons in popular culture.
