The bite force of Deinosuchus has been estimated to be 18,000 N (1,835 kgf; 4,047 lbf) [8] to 102,803 N (10,483 kgf; 23,111 lbf). [19] Deinosuchus had a secondary bony palate, which would have permitted it to breathe through its nostrils while the rest of the head remained submerged underwater. [20]
Deinonychus (/ d aɪ ˈ n ɒ n ɪ k ə s / [1] dy-NON-ih-kəs; from Ancient Greek δεινός (deinós) 'terrible' and ὄνυξ (ónux), genitive ὄνυχος (ónukhos) 'claw') is a genus of dromaeosaurid theropod dinosaur with one described species, Deinonychus antirrhopus.

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 ...
The bite force of Deinosuchus may have measured 23,000 lbf (100 kN), [36] even greater than that of theropod dinosaurs like Tyrannosaurus. [ 59 ] Crocodilian teeth vary from dull and rounded to sharp and pointed. [ 36 ]
The weight had previously been estimated between 2 tonnes (2.2 short tons) and 12 tonnes (13 short tons). Enormous sizes were also suggested by comparing the arms with those of tyrannosaurs, even though members of that group did not have large arms in proportion to their body size.

The largest known land-dwelling artiodactyl was Hippopotamus gorgops with a length of 4.3 m (14 ft), a height of 2.1 m (6 ft 11 in), and a weight of 5 t (11,000 lb), [63] with its closely related European descendant, Hippopotamus antiquus, rivaling it, estimated to be 14.1 ft (4.3 m) in length and 7,700–9,300 lb (3,500–4,200 kg) in weight.
Sarcosuchus is a distant relative of living crocodilians, with fully grown individuals estimated to have reached up to 9 to 9.5 m (29.5 to 31.2 ft) in total length and 3.45 to 4.3 metric tons (3.80 to 4.74 short tons) in weight. [2] It had somewhat telescoped eyes and a long snout comprising 75% of the length of the skull.
