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"

#Welsh 'weird wonder' #fossils add piece to puzzle of #arthropod #evolution https://phys.org/news/2022-11-welsh-weird-fossils-piece-puzzle.html
#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.
