Sarcosuchus (/ ˌ s ɑːr k oʊ ˈ s uː k ə s /; lit. ' flesh crocodile ') is an extinct genus of crocodyliform and distant relative of living crocodilians that lived during the Early Cretaceous, from the late Hauterivian to the early Albian, 133 to 112 million years ago of what is now Africa and South America.
Deinosuchus (/ ˌ d aɪ n ə ˈ sj uː k ə s /) is an extinct genus of alligatoroid crocodilian, related to modern alligators and caimans, that lived 82 to 73 million years ago (Ma), during the late Cretaceous period. The name translates as "terrible crocodile" and is derived from the Greek deinos (δεινός), "terrible", and soukhos ...
Lolong (died 10 February 2013) was the largest crocodile ever held in captivity. He was a saltwater crocodile (Crocodylus porosus) measured at 6.17 m (20 ft 3 in), and weighed 1,075 kg (2,370 lb), making him one of the largest crocodiles ever measured from snout-to-tail.
A pair of researchers with the University of Iowa decided to re-examine existing fossils of the Deinosuchus, a prehistoric ancestor of crocodiles and alligators estimated to be about 33-feet-long ...
Rhamphosuchus crassidens jaws An 1868 illustration of specimens of R. crassidens (top and center) compared to other crocodylian fossils from the Sewalik Hills. Historically, many palaeontologists estimated that it was one of the largest, if not the largest crocodylian that ever lived, reaching an estimated length of 15 to 18 m (49 to 59 ft). [2]
The American crocodile is also one of the largest crocodile species, with large males in the southern part of their range reported to approach 6.1 m (20 ft) in size. Based on projections from various skulls, the largest males may have reached 6–7 m (20–23 ft) in length, and their predicted mass reached up to 1,283 kg (2,829 lb). [120]
The largest known marsupial, and the largest metatherian, is the extinct Diprotodon, about 3 m (9.8 ft) long, standing 2 m (6 ft 7 in) tall and weighing up to 2,786 kg (6,142 lb). [48] Fellow vombatiform Palorchestes azael was similar in length being around 2.5 m (8.2 ft), with body mass estimates indicating it could exceed 1,000 kg (2,200 lb).
Erythrosuchus was the largest predator of its time, and was around 4.75–5 m (15.6–16.4 ft) long. [3] [4] It walked on all fours and had limbs positioned semivertically under its body, unlike the more sprawling gait of most earlier reptiles. Its head was large and theropod-like, reaching a length of 1 m (3.3 ft), and had sharp, conical teeth ...
