Arechia
Arechia is an extinct genus of stingaree from the Eocene epoch. It is the oldest known stingaree genus, though molecular data suggests they diverged from Butterfly rays about 75 million years ago or from Deepwater stingrays around the time of the K-Pg transition. The type species, A. arambourgi, is known from isolated teeth found in the Ypresian deposits of Ouled Abdoun, Morocco. It is named for Camille Arambourg, who originally ascribed these teeth to Raja praealba in 1952. Henri Cappetta revised the species in 1983, erecting this genus for those Arambourg called males in this genus and placed the ones he called females in . The second species, A. crassicaudata is from the Ypresian-age Bolca Lagerstätte of Italy and is known from several articulated individuals. This species was described
