Megalodon may have been warm blooded, new study suggests

So, I have always believed that some dinosaurs were warm blooded.

Like Rhinos are, yet are so similar to Triceratops and similar.

And the theory that Chickens have evolved from T Rex's. Which may have had feathers.

So now it seems Meg may have been warm blooded, too.

So, what say you ATS?

"By examining isotopes found in the tooth enamel of the megalodon, scientists have determined that this prehistoric giant could maintain a body temperature approximately 13 degrees Fahrenheit (7 degrees Celsius) warmer than the surrounding water.

This is a groundbreaking finding which is expanding our understanding of sea animals."

It seems odd that today's mackerel sharks are able to survive but the Meg could not survive back then.

Today, their descendants include the great white and thresher sharks. Unlike most fish, which are cold-blooded, mackerel sharks possess the unique ability to maintain body temperatures higher than the surrounding water.

Mods, not sure if this is in the right place?

Please move if not.

Interesting.

Just hope someone doesn't post the fake photo of a "Meg" next to a U Boat!

Why not just like any other modern shark? They have a countercurrent exchanger thingy they use to warm up and keep it going with just using muscles. Some hold their breath for a really long time, keeps warmth in..

But yeah, ancient, bigger sharks may have used heat also from the large amounts of meat being digested in their bodies too, would make them kinda warm blooded, but still not as mammals for example.

Mother F@@@@r

If sharks ever evolve legs we are done for

This would be the ultimate of karmetic reversals.

Once, the top of the food chain, to become one of the lowest, that is bred for consumption.

Cool find.

Also, if Octopus lived longer and evolved to live on land......

Good point.

But what about Rhinos?

Giraffes look like some Dinosaurs too.

So maybe because of the alleged asteroid strike back then, Meg's large size, as with other large dinos, could not find enough food to survive, whereas smaller mammals could. There I answered my own question, or rather the Smithsonian did, maybe.

According to Penn State researcher Russ Graham, the lifestyles of mammals gave them an advantage when the asteroid struck the area that is today's Yucatan peninsula about 65 million years ago. In response to a "probing question" published on the university's website, Graham opined that mammals that used burrows or lived in aquatic environments would have been shielded from the intense heat that briefly followed the impact. Once the heat was off, mammals could come back out and make the most of the remaining food resources. There may not have been enough food for dinosaurs, but the more generalized tastes of mammals allowed them to hang on.

Yes.

But, crocs and alligators? Komodo Dragons?

Then there is the theory that fish evolved over millennia to breath air when their ponds dried up.

Generally if a pond dries up, the fish die. They don't have millennia to evolve?

So are we done with discussing Meg? LOL

I have no idea, thanks for bringing this to my attention. Did not know there was a mystery there.

Not yet, mate. Wide ranging discussion and all.

Well as for kimodo dragons and other cold blooded mammals they depend on environmental heat so totally different from Meg's needs.

a reply to: quintessentone

Maybe.

But it's always good to challenge stuff.

Yeah, you would think so wouldn't you.

Megalodon being Warm Blooded would explain the Creatures massive size and power but would also explain it's sudden disappearance.

The odds were always 50/50. Some years back they started rethinking that many "classic dinosaurs" as depicted in the mainstream may have been covered in feathers. They espouse with near certainty how the eyes of a Raptor worked, despite never having actually had said eyepiece. Others in the field of know-it-all-ism a few year back claimed to have discovered a xxx-light-years-away star with Earth-like satelites in orbit. Sol went from 9 planets to 8. Does anyone really know? I've watched, read and heard enough to form the opinion that half of the time, maybe more, they make stuff up to sound important.

Was Magalodon warm blooded? Hurry, go get the dice!

Agreed!
