The genus was named after the ancient Roman town of
Abrittus, located near the present Bulgarian city of
Razgrad. There are several described species of
Abrytasites, including A.
thieuloyi, A.
julianyi, and A.
neumayri. They are inflated, with constrictions, have rather thick ribs springing irregularly, singly or in pairs, from umbilical bullae. Their inner whorls closely resemble types species of
Valdedorsella. This animal lived 125–136.4 million years ago during the
Hauterivian and the
Barremian in Europe and western Africa. == See also ==
