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.
Lisowicia compared to a human. The plant-eating dicynodont Lisowicia bojani is the largest-known of all non-mammalian synapsids, at about 4.5 m (15 ft) long, 2.6 m (8 ft 6 in) tall, and 9,000 kg (20,000 lb) in body mass.
Livyatan and megalodon were likely the apex predators of this area during this time. [24] [28] Reconstruction of Livyatan (left) next to Cetotherium (right) L. melvillei is also known from the Bahía Inglesa Formation of Chile, whose fossiliferous beds are dated between the Tortonian and Messinian 9.03–6.45 mya. Like the Pisco Formation, the ...
Scientists don't know for sure whether the megalodon ever lived in Mississippi even if some of its teeth were found in the Magnolia State. National Megalodon Day is June 15. Here are 5 things to ...
Increased postcanine size can be correlated with the evolution of other physiological traits [17] [21] [22] [23] Inverse trends of brain mass and molar size point to diet and food processing as a linking factor; encephalization is a crucial consideration in the development of tool usage and extraoral food processing that was observed in Homo ...
A new study finds that megatooth sharks’ warm-blood adaptation and giant size may have played a role in their extinction.
Prehistoric Predators is a 2007 National Geographic Channel program based on different predators that lived in the Cenozoic era, including Smilodon and C. megalodon.The series investigated how such beasts hunted and fought other creatures, and what drove them to extinction.
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. [3] [8] [9] However, due to its co-existence with O. megalodon during the Miocene and Pliocene epochs, it is regarded as a morpho-species. [3]
