A glimpse at the ontogeny of the fossil neobatrachian frog calyptocephalella canqueli from the Deseadan (Oligocene) of Patagonia, Argentina

Mostrar todas las versiones(3)

Two fossil tadpoles collected in the Deseadan levels (Oligocene) at the Scarritt Pocket locality of central Patagonia are studied herein. These specimens, which show different degrees of skeletal development, have been assigned to the neobatrachian Calyptocephalella canqueli based on the morphology...
