Finally, the complete Otodus obliquus to O. megalodon progression became clear and has since gained the acceptance of many shark researchers. [8] Within the Otodus lineage; O. chubutensis is the succeeding species of O. angustidens and is followed by O. megalodon. [3] In short, O. chubutensis is considered a possible ancestor of O. megalodon.
Otodus megalodon (/ ˈ m ɛ ɡ əl ə d ɒ n / MEG-əl-ə-don; meaning "big tooth"), commonly known as megalodon, is an extinct species of giant mackerel shark that lived approximately 23 to 3.6 million years ago (Mya), from the Early Miocene to the Early Pliocene epochs.
Comparative studies of the centrum radii and growth rings on the vertebrae of O. obliquus and the extant great white shark through X-rays have concluded that the sizes of the vertebrae at birth are similar, meaning that the offspring of both species would have the same size (between 1.1 and 1.6 m (3.6 and 5.2 ft) in length); they also revealed ...
A new study posits that the ancient megalodon shark was longer and slimmer than previously believed. The ancient shark has been compared to the great white, but it may have more closely resembled ...
Squalicorax, commonly known as the crow shark, is a genus of extinct lamniform shark known to have lived during the Cretaceous period. The genus had a global distribution in the Late Cretaceous epoch. Multiple species within this genus are considered to be wastebasket taxon due to morphological similarities in the teeth.
“We waited for one of the rods to go off.”
The silhouettes shown here depict megalodon as a robust Lamnid-like shark and are based on the estimated body dimensions proposed by Cooper et al. and a life restoration by Oliver Demuth. [1] However, due to the limited information on life appearance, other body plans have been proposed, and megalodon could have looked substantially different ...
Megalodons, the huge prehistoric sharks depicted in movies such as “The Meg,” had more slender bodies than was previously thought, according to a new study. Megalodons, the huge prehistoric ...
