Mongolepidida
Extinct order of cartilaginous fishes
From Wikipedia, the free encyclopedia
Mongolepidida is an order of primitive chondrichthyans (cartilaginous fishes) that lived during the Ordovician and Silurian periods of Asia and North America.[1][2][3] They are only known from scales, so their appearance is largely unknown. The oldest of these scales, belonging to Solinalepis levis, have been dated back to the Sandbian age of the Ordovician, making mongolepidids some of the oldest chondrichthyans known to date.[1][4]
