Jouve and colleagues suggested in 2008 that juvenile marine crocodyliforms lived in freshwater environments as do modern marine crocodile juveniles, which would have helped them survive where other marine reptiles became extinct; freshwater environments were not so strongly affected by the K–Pg extinction event as marine environments were.

The cost to clean up after an asteroid or comet impact would cost billions to trillions of dollars, depending on the location impacted. [19] [20] An impact in New York City (the 16th most populated city in the world) could cost billions of dollars in financial losses and it could take years for the financial sector (i.e. stock market) to ...
Mosasaurus (/ ˌ m oʊ z ə ˈ s ɔːr ə s /; "lizard of the Meuse River") is the type genus (defining example) of the mosasaurs, an extinct group of aquatic squamate reptiles.It lived from about 82 to 66 million years ago during the Campanian and Maastrichtian stages of the Late Cretaceous.
Jan Smit reported that the only foraminiferan species to survive the Cretaceous was Guembelitria cretacea, and that all subsequent foraminiferans were its descendants. [62] Ferguson and Joanen proposed that an increasingly hot and dry climate could have skewed the ratio of male to female dinosaur hatchlings, leading to their extinction. [23]
Once grabbed and dragged into water, it is unlikely the victim will escape. Analysis of attacks show most-such attacks take place when crocodiles are guarding nests or newly hatched young. [152] Saltwater crocodiles have been implicated in over 1,300 attacks on humans between 2010 and 2020, almost half of which fatal. [151]
The American crocodile (Crocodylus acutus) is a species of crocodilian found in the Neotropics.It is the most widespread of the four extant species of crocodiles from the Americas, with populations present from South Florida, the Caribbean islands of Cuba, Jamaica, Hispaniola, [4] and the coasts of Mexico to as far south as Peru, Ecuador, Colombia, and Venezuela.
Crocodiles (family Crocodylidae) or true crocodiles are large, semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia.The term “crocodile” is sometimes used more loosely to include all extant members of the order Crocodilia, which includes the alligators and caimans (both members of the family Alligatoridae), the gharial and false gharial (both ...
After it had been earlier interpreted as a fish, a crocodile, and a sperm whale, the first to understand its lizard affinities was the Dutch scientist Adriaan Gilles Camper in 1799. In 1808, Georges Cuvier confirmed this conclusion, although le Grand Animal fossile de Maëstricht was not actually named Mosasaurus (' Meuse reptile') until 1822 ...
