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.
Deinocheirus (/ ˌ d aɪ n oʊ ˈ k aɪ r ə s / DY-no-KY-rəs) is a genus of large ornithomimosaur that lived during the Late Cretaceous around 70 million years ago. In 1965, a pair of large arms, shoulder girdles, and a few other bones of a new dinosaur were first discovered in the Nemegt Formation of Mongolia.
The largest change was prompted by entomologist Willi Hennig's work in the 1950s, which evolved into modern cladistics. For specimens known only from fossils , the rigorous analysis of characters to determine evolutionary relationships between different groups of animals ( clades ) proved incredibly useful.
Congregating into herds may have evolved for defense, for migratory purposes, or to provide protection for young. There is evidence that many types of slow-growing dinosaurs, including various theropods, sauropods, ankylosaurians, ornithopods, and ceratopsians, formed aggregations of immature individuals.
In Greek mythology, Dino or Deino (Ancient Greek: Δεινώ means "dread" or "eddy, whirlpool") may refer to the following divinities: Deino, also called Persis, [ 1 ] one of the Graea who were daughters of the sea-deities Phorcys and Ceto . [ 2 ]
Likewise in Asia, Prodeinotherium is known from the early Miocene strata in the Bugti Hills, and continued into the middle Miocene Chinji Formation, where it was replaced by D. indicum. While these Miocene deinotheres were dispersed widely and evolved to huge elephant sizes, they were not as common as the contemporary (but smaller) Elephantoidea .
Deinococcus radiodurans does not form endospores and is nonmotile. It is an obligate aerobic chemoorganoheterotroph, i.e., it uses oxygen to derive energy from organic compounds in its environment. It is often found in habitats rich in organic materials, such as sewage, meat, feces, or, soil, but has also been isolated from medical instruments ...
The American Museum of Natural History incorporated the skull and jaw fragments into a plaster restoration, modeled after the present-day Cuban crocodile. Colbert and Bird stated this was a "conservative" reconstruction, since an even greater length could have been obtained if a long-skulled modern species, such as the saltwater crocodile had ...
