hello basilosaurid nation i have been thinking about the perucetus colossus and his tiny little legs !

[id: three drawings of a whale-like animal. they are roughly seal-shaped in terms of body, with a round flat tail and a small protruding oval head. all three have small back legs and feet. the first, coloured purplish, has flipper-like anterior appendages. the second, coloured blue, has big hands at the end of long, wide arms. the third is greenish, and has traditional finger-less whale fins. end id]

Did another lorge whale warmup lol I'm really taken with the idea of a huge benthic whale. I think it's because I've always been rather taken with steller's sea cows too. I hope more fossils are found, I'd love a skill to confirm what kind of diet it had :'3

Jaune: I'll see you guys later.

Ruby: Huh? Where are you going?

Jaune: I'm gonna go eat in my room.

Nora: We can do that?

Weiss: Sit down and eat, you antisocial buffoon!

Jaune: ...Okay.

Cardin: I'm telling you, I know what I saw! There was something by the pool last night, tearing apart something huge!

Russel: Cardin, I normally believe ya, but it just sounds too weird.

Dove: Yeah, like, a deer carcass in the pool? Pretty sure we'd get an announcement about that.

Lark: Not to mention the crocodile you saw eating it.

Cardin: That wasn't a crocodile! It was... It was something else! Something out of a horror film!

Jaune: (Cutting off the legs on his nuggies, Wishing he could eat in private)

Fun Fact! In 1933, in the African Kasai Valley, a hunter named John Johnson took a photo of an alleged dinosaur while hunting elephants. The elephants he intended to shoot were in fact hunted by a bipedal creature with red scales and black stripes. He shot this creature, but it retreated. On his return to camp, he found the creature again eating a rhinoceros near the water.

Nora: WOW! You are HUGE!

Jaune: Um, h-hi... I'm Jaune.

Nora: Where were you on the bullhead?! How'd you even fit?!

Ren: Nora, please.

Jaune: They, uh... They had to call in another bullhead for me.

Fun Fact! A recently discovered early whale, the basilosaurid Perucetus Colossus has the heaviest animal bone mass to have ever been discovered, even outsizing the giant Blue Whale.

Sperm Whale!Faunus Jaune Arc & Shark!Faunus Yang Xiao Long & Leviathan Melvillei!Faunus Papa Arc & Otodus Megalodon!Faunus Raven Branwen

Jaune: Just you and me, Yang.

Yang: Yeah... Only one of us can be the top fighter in this ring, and it's gonna be me.

Pyrrha: Why are those two always fighting?

Blake: For as long as I've known Yang, she and Jaune have always been fighting. It might even date back to their ancestors.

Meanwhile...

Papa Arc: Make the first move, Branwen...

Raven: Hmph! Ladies first, Arc...

Fun Fact! Leviathan Melvillei is an ancient ancestor of the sperm whale, equipped with teeth on it's top AND bottom jaw. It is argued whether it hunted Megalodon, were hunted by it, or simply competed would attack the other given the opportunity. The third is the often agreed upon consensus.

---------------------------------------------------

Giganotosaurus!Faunus Jaune & Tyrannosaurus!Faunus Saphron

Saphron: I took a test today! I aced it!

Mama Arc: Well done, Saphron! And how did you do, Jaune?

Jaune: Uh... W-Well, I think I'm improving, but-

Mama Arc: Jaune...

Jaune: ...I got a D+.

Fun Fact! Giganotosaurus is thought to be the largest theropod dinosaur discovered. However, despite have a much larger skull, and internal model of the brain casing shows that it may have had a smaller brain than the Tyrannosaurus.

How did I only JUST find out that a NEW WHALE just dropped and it’s likely to have been HEAVIER than a fucking BLUE WHALE. THIS IS SO RAD. LOOK AT THIS THING. FUCJING-

IT’S SO GOOFY, I LOVE IT

ALSO HOW DID I MISS THIS NEWS FOR A WHOLE-ASS MONTH ??????

Peruvian fossil challenges blue whales for size

3 August 2023

By Jonathan Amos, Science correspondent

Scientists have identified a new candidate for the heaviest ever animal on Planet Earth.

It's an ancient, long-extinct whale that would have tipped the scales at close to 200 tonnes.

Only some of the very biggest blue whale specimens might have rivalled its heft, researchers say.

The creature's fossilised bones were dug up in the desert in southern Peru, so it has been given the name Perucetus colossus.

Dating of the sediments around the remains suggests it lived about 39 million years ago.

"The fossils were actually discovered 13 years ago, but their size and shape meant it took three years just to get them to Lima (the capital of Peru), where they've been studied ever since," said Dr Eli Amson, a co-worker on the discovery team led by palaeontologist Dr Mario Urbina.

Eighteen bones were recovered from the marine mammal - an early type of whale known as a basilosaurid.

These included 13 vertebrae, four ribs and part of a hip bone.

But even given these fragmentary elements and their age, scientists were still able to decipher a huge amount about the creature.

In particular, it's evident the bones were extremely dense, caused by a process known as osteosclerosis in which inner cavities are filled.

The bones were also oversized, in the sense they had extra growth on their exterior surfaces - something called pachyostosis.

These weren't features of disease, the team said, but rather adaptations that would have given this large whale the necessary buoyancy control when foraging in shallow waters.

Similar bone features are seen for example in modern-day manatees, or sea cows, which also inhabit coastal zones in certain parts of the world.

"Each vertebra weighs over 100kg, which is just completely mind-blowing," said co-worker Dr Rebecca Bennion from the Royal Belgian Institute of Natural Sciences in Brussels.

"It took several men to shift them out into the middle of the floor in the museum for me to do some 3D scanning.

The team that drilled into the centre of some of these vertebrae to work out the bone density - the bone was so dense, it broke the drill on the first attempt."

When confronted with a skeleton of a long-extinct species, scientists use models to try to reconstruct the body shape and mass of the animal.

They do this based on what they know about the biology of comparable living creatures.

It is predicted Perucetus would have been about 17-20m in length, which is not exceptional.

But its bone mass alone would have been somewhere between 5.3 and 7.6 tonnes.

And by the time you add in organs, muscle and blubber, it could have weighed - depending on the assumptions - anywhere between 85 tonnes and 320 tonnes.

Dr Amson, a curator at Germany's State Museum of Natural History Stuttgart, uses a median number of 180.

The largest blue whales recorded during the era of commercial exploitation were at this scale.

"What we like to say is that Perucetus is in the same ball park as the blue whale," he told BBC News.

"But there's no reason to think that our individual was particularly big or small; it was likely just part of the general population.

So it's worth keeping in mind that when we use the median estimate, it's already at the very upper ranges of what blue whales can measure."

One of the comparators used by the research team in its investigations is a blue whale that will be very familiar to anyone who has visited the Natural History Museum in London.

Nicknamed Hope, this animal's skeleton took pride of place at the institution when it was hung from the ceiling in the main hall in 2017.

But before being installed, the skeleton was scanned and described in great detail and is now an important data resource for scientists across the world.

In life, Perucetus' skeletal mass would have been two to three times that of Hope, even though the London mammal was a good five metres longer.

Richard Sabin, the curator of marine mammals at the NHM, is thrilled by the new find and would love to bring some aspect of it to London for display.

"We took the time to digitise Hope - to measure not just the weight of the bones but their shape as well, and our whale has now become something of a touchstone for people," he said.

"We don't get hung up on labels - like 'which was the largest specimen?' - because we know science at some point will always come along with new data.

What's amazing about Perucetus is that it demonstrated so much mass some 30 million-plus years ago when we thought gigantism occurred in whales only 4.5 million years ago."

Perucetus colossus is reported in the journal Nature.

While blue whales are sleek, fast-swimming divers, Perucetus was a very different beast. The researchers suspect that it drifted lazily through shallow coastal waters like a mammoth manatee, propelling its sausage-like body with a paddle-shaped tail. “This is a weird and stupendous fossil, for sure,” said Nicholas Pyenson, a paleontologist at the Smithsonian National Museum of Natural History, who was not involved in the study. “It’s clear from this discovery that there are so many other ways of being a whale that we have not yet discovered.” The head of Perucetus would have adaptations for whichever way of life it pursued. “I would love to see the skull of this guy,” Dr. Thewissen said.

PERUCETUS COLOSSUS

When I read about this news, I was amazed. Actually, I'm working on a personal research. I want to create my own encyclopedia on whale ancestors. I'm really addictive to them. The more I learn, more I'm interested. So, if you have any recommandations for my readings, searchings, I'll take it!

Now that I know this new one, I can't wait to be able to read the official scientific article.

This animal could be the heaviest... EVER! More than the blue whale! Incredible, don't you think ?
