In life, archosaurs have a horny sheath over this bone, which extends the length. Ostrom looked at crocodile and bird claws and reconstructed the claw for YPM 5205 as over 120 millimetres (4.7 in) long. [2] The species name antirrhopus means "counter balance", which refers to Ostrom's idea about the function of the tail.
In 1970, Rozhdestvensky re-examined the claws and suggested a possible function specialized in opening termite mounds or a frugivore diet. [2] Barsbold in 1976 suggested that the unusual claws of Therizinosaurus may have been employed to impale or dig up loose terrain, however, he pointed out their notorious fragility upon impact. [4]
Life restoration. Machairasaurus was a small bipedal theropod, measuring around 1.5 m (4.9 ft) long. The describers established a single autapomorphy, unique derived trait: the hand claws are very elongated and blade-like in side view, with a length four times that of the joint height. The long claws would be proof that basal oviraptorids used ...
Camarasaurus (/ ˌ k æ m ər ə ˈ s ɔː r ə s / KAM-ər-ə-SOR-əs) is a genus of sauropod dinosaur that lived in North America during the Late Jurassic period.Its fossil remains have been found in the Morrison Formation, dating to the Kimmeridgian and Tithonian ages of the Jurassic, between 155 and 145 million years ago (mya).
The largest tracks are 50 cm (20 in) long with a pace of 130 cm (51 in), and the smallest is 36 cm (14 in) long with a pace of 100 cm (39 in). The tracks are tridactyl (three-toed) and have large and coarse digits, with prominent claw impressions. Impressions of the digits occupy most of the track-length, and one track has a thin heel.
What was 21-feet tall, looked like a T-rex and was covered in feathers? It was the Cryolophosaurus, of course! This eccentric beast roamed the Earth during the early Jurassic Period, around 188 to ...
Similar to tyrannosaurs, it had small, conical teeth at the front of its jaws, and longer, more curved teeth near the back. The hand claws of Megaraptor were very long and strongly curved, with the claw of the first finger measuring 35 cm (14 in). The claw of the third finger was the smallest, only 6.5 cm (2.6 in) in length.
Based on the ratio between the length of the snout and the length of the rest of the skull in iguanodonts, the total length of the holotype's skull may have been 83.3 cm (2 ft 9 in) in life. [1] Life restoration. Lurdusaurus may have had 12 to 14 neck vertebrae. Therefore, the maximum length of the neck is 1.6 m (5 ft 3 in).
