The Punta Judas Formation is a geologic formation in Costa Rica. It preserves fossils dating back to the Middle Miocene period. [1]
Negaprion is a genus of requiem sharks in the family Carcharhinidae. It contains the two extant species of lemon sharks: the lemon shark of the Americas, and the sicklefin lemon shark of the Indo-Pacific. Both species are large, slow-moving, bulky sharks inhabiting shallow coastal waters, and can be identified by their short, blunt snouts, two dorsal fins of nearly equal size, and uniform yellowish brown or gray coloration.
Eutatus is an extinct genus of large armadillos of the family Chlamyphoridae. It was endemic to South America from the Early Miocene to Late Pleistocene, living from 17.5 Ma-11,000 years ago, with possible survival into the early Holocene and existing for approximately 17.49 million years. Based on carbon isotope ratios, it is thought to have been an herbivore that fed on grasses.
Negaprion eurybathrodon is an extinct species of lemon shark, which existed globally from the Late Eocene to the Pliocene. It was described by Blake in 1862.
The Penita Formation is a geologic formation in Costa Rica. It preserves fossils dating back to the Neogene period.

Hindsiclava consors is a species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies.
The Jama Formation is a Pliocene to Early Pleistocene geologic formation in Ecuador. The claystones and sandstones were deposited in an coastal environment. The age of the Jama Formation is constrained by 40Ar/39Ar dating of tephra beds. The formation is correlated to the Charco Azul Formation of western Panama and southeastern Costa Rica.
The Onzole Formation is an Early Pliocene geologic formation in the Borbón Basin of northwestern Ecuador. The formation consists of a shallow marine sandstone member containing many fish fossils, among which megalodon, and a deep water member comprising tuffaceous shales and mudstones containing gastropods, bivalves and scaphopods.
