[2] The formation was deposited under lacustrine conditions in a shallow carbonate lake, with some exposure events in the sedimentary sequence.

Imprints of dinosaurs were made in carbonate mud, after they were infilled with marl.

Dinosaur tracks have been assigned to sauropods, theropods and ornithopods.

[3] An indeterminate titanosauriform sauropod humerus (MDS-VPCR, 214) similar to Duriatitan has been found in the formation,[4] as well as a camarasaurid teeth and an indeterminate macronarian fragment of a dentary (MDS-VPCR,851).

[5] The municipality of Mambrillas de Lara has created a dinosaur park.
