Brachydelphis


Brachydelphis is a genus of pontoporiid known from the Late Miocene Pisco Formation of Peru and the Bahía Inglesa Formation of Chile.

Taxonomy

Two species are recognized, B. jahuayensis and B. mazeasi. B. mazeasi has a shortened rostrum that gives Brachydelphis its name, B. jahuayensis differs from the type species in having a longer snout and higher tooth count.

Biology

Brachydelphis mazeasi was capable of suction-feeding judging from its short rostrum, but the longer rostrum of B. jahauyensis allowed it to capture small prey items.
