Peru: Researchers in Peru have discovered the heaviest animal in Earth’s history. The blue whale was said to be the largest, but on 3rd August 2023, scientists announced that they had identified a fossil of a creature that may weigh up to 200 tonnes. The research was published in Nature.
The study took place in Lima (the capital of Peru). The fossils were discovered 13 years ago in southern Peru. But it took three years to get it there in the Capital. The creature’s fossilised bones were dug up in the desert, so it’s been called Perucetus colossus, meaning colossal Peruvian whale. Scientists assume that it lived about 39 million years ago.
“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 Mr. Giovanni Bianucci of the University of Pisa in Italy, lead author of the research.
The minimum mass estimate for Perucetus was 85 tonnes, with an average estimate of 180 tonnes. The biggest-known blue whale weighed around 190 tonnes, though it was longer than Perucetus at 33.5 metres (110 feet), as per the statement.
“Because of its heavy skeleton and, most likely, its very voluminous body, this animal was certainly a slow swimmer. This appears to me, at this stage of our knowledge, as a kind of peaceful giant, a bit like a super-sized manatee. It must have been a very impressive animal, but maybe not so scary,” palaeontologist Mr. Olivier Lambert of the Royal Belgian Institute of Natural Sciences in Brussels remarked.
