Also known as Crocodilus hartti type locality; Plantaforma

Where: Bahia, Brazil (12.9° S, 38.5° W: paleocoordinates 11.6° S, 5.3° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Ilhas Group, Late/Upper Hauterivian to Late/Upper Hauterivian (136.4 - 125.5 Ma)

• Lower Cretaceous Recôncavo Basin, Bahia Supergroup, Ilhas Group (Late Hauterivian–Early Barremian)

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; lithified, pebbly conglomerate and green, sandy shale

The conglomerate is composed of more or less rounded pebbles of gneiss, granite, quartz, and other crystalline rocks, and occasionally of sandstone; the whole forming an extremely hard rock. The pebbles vary in size from the finest gravel to large boulders."
