Did the megalodon look like and behave like the great white is a question that will likely continue to be asked for many years. But I am not among them.
Megalodon Shark Facts and Information: The Details
So don't worry if you find a tooth with very small cusps, and can't tell if it's a juvenile megalodon or a subauriculatus; it's a Megatooth shark, leave it at that!
Most sharks have 8 rigid fins A pair of pectoral fins, a pair of pelvic fins, one or two dorsal fins, an anal fin Free matchmaking online a caudal fin tail.
By using these fossil remains researchers and scientists have used technology and their understanding of shark anatomy to reconstruct how the megalodon looked and behaved. Chondrichthyes have skeletons made up of cartilage rather than bone, and lack a swim bladder. There are those who want desperately to believe that somewhere, perhaps in the deep ocean, Megalodon still lives.
With only two known specimens, dissection was out of the question. For more information, here is a great article by Lutz Andres about megalodon evolution.
True, but new evidence suggests that the rate of manganese dioxide deposition is highly variable, dependent upon among other factors regional and seasonal fluctuations in primary productivity by phytoplankton.
The discovery of new species - even large and spectacular ones like Megachasma - does not, of itself, imply that a particular species, Megalodon, will necessarily be re-discovered.
Also learn about how you can be a part of the conservation team. The megatooth shark was clearly a top predator of its time.
Unfortunately these debates and arguments have made it difficult to determine the relationship between the two species and our limited knowledge of the megalodon makes it hard to come to a concrete yes or no decision.
This lineage example is not complete, as it is missing the Kazakhstan specimens, but it shows the general broadening and cusp reduction. A full body CT scan image of the side of the fish pictured The scans allowed the researchers to hone in on the fish's skeletal structure from many different angles and digitally dissect parts of the fish.
They estimate that the tiny fish they found has between 1, to 2, individual teeth, or ten times what all other known clingfish have.
Unfortunately, Megalodon sharks were warm water sharks and could not go into the cold arctic waters. One of the best examples of megalodon predation evidence is shown in the image above. Using tooth and jaw reconstructions from associated fossils, paleontologists have calculated possible size estimates.
Food migration While some of the megalodons food supplies may have become extinct over time other species may have become migratory in order to maintain their own life and stability. Orcas, or Killer Whales are large marine mammals that are intelligent and hunt in packs.
Towards the end of their extinction large environmental changes and ocean cooling can be found occurring throughout various parts of the world which may have caused the megalodon to seek warmer environments or face possible death.
Why the megalodon may have become extinct When it comes to determining why the megalodon became extinct no one really knows what happened.
A mirror like layer in the back of the eye called the tapetum lucidum the same found in catsdoubles the intensity of incoming light and allowing them to see exceptionally well in dim conditions.
It's fossils are almost always found in areas associated with fossil whale bone.
