Daeodon shoshonensis
Daeodon, one of the largest, if not the largest, entelodont artiodactyls, lived 25-18 million years ago in North America. The 3.6 m (12 ft) long, about 1.8 m at the shoulder, 90 cm long skulled, 600 - 1000 kg mass animal strongly resembled a giant, monstrous pig or warthog, possessing huge jaws with prominent tusks and flaring cheekbones. It possibly was a huge, bone-crushing scavenger and predator, found at Agate Springs Quarry. It had long skull bones under its eyes and bony protrusions on the lower jaw, not dissimilar to the 'warts' of the warthog, which may have supported jaw muscles. The well-known genus Dinohyus ("terrible pig") has now been synonymized with Daeodon, as the latter is the earlier name, having priority.
Ceratosaurus dentisulcatus
Ceratosaurus meaning "horned lizard", in reference to the horn on its nose (Greek κερας/κερατος, keras/keratos meaning "horn" and σαυρος/sauros meaning "lizard"), was a large predatory theropod dinosaur from the Late Jurassic Period (Kimmeridgian to Tithonian), found in the Morrison Formation of North America, in Tanzania and Portugal. It was characterized by large jaws with blade-like teeth, a large, blade-like horn on the snout and a pair of hornlets over the eyes. The forelimbs were powerfully built but very short. The bones of the sacrum were fused (synsacrum) and the pelvic bones were fused together and to this structure (Sereno 1997) (i.e. similar to modern birds). A row of small osteoderms was present down the middle of the back. Ceratosaurus was a fairly typical theropod, with a large head, short forelimbs, robust hind legs, and a long tail. Uniquely among theropods, Ceratosaurus possessed dermal armor, in the form of small osteoderms running down the middle of its back. The tail of Ceratosaurus comprised about half of the body's total length. It was thin and flexible, with high vertebral spines. Specimen USNM 4735, the first discovered skeleton and holotype of Ceratosaurus nasicornis, was an individual 5.3 m (17 ft) or 5.69 m (18.7 ft) in length according to separate sources. It is not clear whether this animal was fully grown. Three additional skeletons discovered in the latter half of the 20th century were substantially larger. The first of these, UMNH VP 5278, was informally estimated by James Madsen to have been around 8.8 m (29 ft) long, but was later estimated at 7 m (23 ft) in length. Its weight was calculated at 980 kg (2,160 lb), 452 kg (996 lb), and 700 kg (1,540 lb) in separate works. The second skeleton, MWC 1, was somewhat smaller than UMNH VP 5278 and might have been 275 kg (606 lb) in weight. The third, yet undescribed, specimen BYUVP 12893 was claimed to be the largest yet discovered, although estimates have not been published. Another specimen (ML 352), discovered in Portugal in 2000, was estimated at 6 m (20 ft) in length and 600 kg (1,320 lb) in weight.
