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 ...
The feeding ecology of megalodon appears to have varied with age and between sites, like the modern great white shark. It is plausible that the adult megalodon population off the coast of Peru targeted primarily cetothere whales 2.5 to 7 meters (8.2 to 23 ft) in length and other prey smaller than itself, rather than large whales in the same ...
One of the most striking fossils around today are the teeth and reconstructed jaws of the megalodon.The jaws of the extinct shark are so big, one or two people can stand inside them.
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 ...
A new study finds that megatooth sharks’ warm-blood adaptation and giant size may have played a role in their extinction.
Megalodon is an extinct genus of bivalve molluscs that reportedly lived from the Devonian to the Jurassic period. [1] It is not clear, however, that all the fossils assigned to Megalodon from that span of time really belong in the same genus. Jurassic relatives of Megalodon such as Pachyrisma grande were closely related to the rudists. [2]
The behemoth clocked in at a whopping 6 1/6 inches in length—roughly the size of a human hand!
The onion test is a way of assessing the validity of an argument for a functional role for junk DNA.It relates to the paradox that would emerge if the majority of eukaryotic non-coding DNA were assumed to be functional and the difficulty of reconciling that assumption with the diversity in genome sizes among species.
