Paranasuchus is an extinct genus of large caiman from the Late Miocene Ituzaingó Formation of Argentina.The type species was originally described as a new species of Caiman, C. gasparinae, in 2013, but a study from 2024 concluded that it differed significantly enough to represent its own genus.
Jacarea is a clade of caimans within the subfamily Caimaninae.Jacarea was first named by Norell in 1988 to include the extant species within the genera Caiman and Melanosuchus, while excluding the dwarf caiman genus Paleosuchus. [1]
Female caimans build a large nest in which to lay their eggs. The nests can be more than 1.5 m (4.9 ft) wide. Female caimans lay between 10 and 50 eggs, which hatch within about six weeks. Once they have hatched, the mother caiman takes her young to a shallow pool of water, where they can learn how to hunt and swim.
The yacare caiman is the largest species in the genus, attaining an average adult length of 2.5 to 3 m (8.2 to 9.8 ft), [5] the spectacled caiman reaches 2 to 2.5 m (6.6 to 8.2 ft), with the female rather smaller, [6] and the broad-snouted caiman is the smallest, more typically measuring 1.8 to 2 m (5.9 to 6.6 ft) for males and 1.2 to 1.4 m (3. ...
Subfamily Osteolaeminae. Genus Osteolaemus. Osteolaemus osborni, Osborn’s dwarf crocodile; Osteolaemus tetraspis, dwarf crocodile (There has been controversy as to whether or not this is actually two species; recent (2010) DNA analysis indicate three distinct species: O. tetraspis, O. osborni and a third, currently unnamed.) [4]
Caimans tend to be more agile and crocodile-like in their movements, and have longer, sharper teeth than alligators. [ 13 ] C. crocodilus , the spectacled caiman , has the widest distribution, from southern Mexico to the northern half of Argentina, and grows to a modest size of about 2.2 m (7.2 ft).
Both species of genus Dracaena, the northern caiman lizard (Dracaena guianensis) and the Paraguay caiman lizard (Dracaena paraguayensis), can have a length of 1.2 m (3.9 ft) and a mass in 4.5 kg (9.9 lb). [175] The largest member of the genus Tupinambis is the gold tegu (Tupinambis teguixin) with a maximum SVL in 40 cm (16 in). [176]
