One study indicated Deinosuchus may have lived for up to 50 years, growing at a rate similar to that of modern crocodilians, but maintaining this growth over a much longer time. Deinosuchus fossils have been discovered in 12 U.S. states, including Texas, Montana, and many along the East Coast. Fossils have also been found in northern Mexico.
Deinosuchus is an extinct genus related to the alligator that lived 80 to 73 million years ago , during the late Cretaceous period. The name translates as "terrible ...
English: A comparison of several size estimates for Deinosuchus, a giant Late Cretaceous crocodilian. The largest credible specimen of modern C. porosus (saltwater crocodile) is also included in the diagram for comparison, as is an average height human.

[113] [114] Debate on megafaunal extinction in Australia has historically centred on whether the extinctions were caused by humans (which most sources estimate arrived in Australia at least 50,000 years ago, spreading to Tasmania later around 42-41,000 years ago [115]), or whether many megafauna species had already gone extinct prior to human ...
The evidence of the forested environment is overwhelmingly supported by petrified wood, rooted gley paleosols, [123] and ubiquitous tree leaves. The presence of the simple and lobed leaves, combined with an extremely high dicot diversity, extinct cycadeoid Nilssoniocladus , Ginkgo , many types of monocots , and several types of conifers is ...
[123] [124] While this was occurring, modern birds were undergoing diversification; traditionally it was thought that they replaced archaic birds and pterosaur groups, possibly due to direct competition, or they simply filled empty niches, [92] [125] [126] but there is no correlation between pterosaur and avian diversities that are conclusive ...
Life restoration of Sarcosuchus imperator. 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]
Due to the fact that there are six to seven different names of sun temples mentioned in primary sources from this period, it is suggested there are at least six different temples. [5] However, there is no specific term for sun temple in ancient Egyptian. [4] The temples were also a source of great wealth and importance in ancient Egypt. [4]
