Skeletal traits indicate Perucetus was related to Basilosaurus, another early whale that was similar in length but less massive.īasilosaurus, however, was an active predator boasting a streamlined body, powerful jaws and large teeth. It must have been a very impressive animal, but maybe not so scary,” said palaeontologist Olivier Lambert of the Royal Belgian Institute of Natural Sciences in Brussels. This appears to me, at this stage of our knowledge, as a kind of peaceful giant, a bit like a super-sized manatee. “Because of its heavy skeleton and, most likely, its very voluminous body, this animal was certainly a slow swimmer. The researchers suspect Perucetus lived like sirenians – not an active predator but an animal that fed near the bottom of shallow coastal waters. No cranial or tooth remains were found, making interpretation of its diet and lifestyle tougher. Other coastal dwellers, like manatees and dugongs, known as sirenians, have heavy bones to help them stay close to the seafloor. Those super-dense bones suggest that the whale may have spent its time in shallow, coastal waters, the authors said. The bones, unusually voluminous, were extremely dense and compact. The results: 13 vertebrae from the whale’s backbone, four ribs and a hip bone. The partial skeleton of Perucetus was discovered more than a decade ago by Mario Urbina from the University of San Marcos’ Natural History Museum in Lima.Īn international team spent years digging them out from the side of a steep, rocky slope in the Ica desert, a region in Peru that was once underwater and is known for its rich marine fossils.

The minimum mass estimate for Perucetus was 85 tonnes, with an average estimate of 180 tonnes. “The main feature of this animal is certainly the extreme weight, which suggests that evolution can generate organisms that have characteristics that go beyond our imagination,” said palaeontologist Giovanni Bianucci of the University of Pisa in Italy, lead author of the research published in the journal Nature. Its scientific name means “colossal Peruvian whale”. It weighed up to 340 metric tonnes, a mass that would exceed any other known animal including today’s blue whale and the largest dinosaurs. The early whale, which lived about 38-40 million years ago during the Eocene epoch, was built somewhat like a manatee and was likely about 20 metres (66ft) long. While today’s blue whale has long held the title, researchers said on Wednesday that fossils of a creature unearthed in Peru called Perucetus colossus could tip the scales. The large, flat, bony plates along its back and its very heavy spiked tail protected stegosaurs from predators.Scientists in Peru have announced a new contender for the heaviest animal in Earth’s history. Instead, the dinosaur used its beak to grind plants to eat. This was a big dinosaur and was up to 30 feet long, but stegosaurs had a very tiny brain the size of a walnut. It walked on all four legs, but stegosaur's back legs were twice as long as its front legs. Stegosaurus was a plant-eating dinosaur that had a sharp spiked tail and plates along its back. Its biggest teeth were over 9 inches long! Adult T-Rexes were huge and grew be to 40 feet long and up to 20 feet tall. This dinosaur had thick scaly skin that was rough and scratchy. Tyrannosaurus rex ate other large dinosaurs, like triceratops, that couldn't defend themselves or run away fast enough. It walked on its back two hind legs and had two short arms with sharp claws. Tyrannosaurus rex was a huge, fierce meat-eating dinosaur that lived in the forest. Adult triceratops grew to be up to 30 feet long and 10 feet tall. Triceratops also had a big bony frill on its head like a huge collar. Instead it charged them with its three sharp horns. Since triceratops walked so slowly, it couldn't run from predators. The smaller horn was right above its nose. The two biggest horns were on the top of the triceratops' head above its eyes. It walked on four legs and had three horns on its face. ![]() Triceratops was a plant eating-dinosaur that looked a lot like a rhinoceros. ![]()
