The Blue Whale is the largest mammal to have ever existed on Earth, according to the internet. However, scientists believe they have discovered a stronger challenger capable of dethroning the ocean giants. On Wednesday, scientists announced an incredible discovery. They discovered the fossil of an early whale called Perucetus colossus in Peru. According to estimates, the species lived 38-40 million years ago during the Eocene epoch and may have even surpassed the bulk of the blue whale, which has long been regarded the heaviest mammal on record.
Perucetus colossus was estimated to be over 66 feet and weighed up to 340 metric tonnes
The Perucetus colossus was estimated to be over 66 feet (20 meters long) and weighed up to 340 metric tonnes, making it heavier than today’s blue whale and even the largest dinosaurs. As a result, the moniker “colossus Peruvian whale” was coined.
The research was published in the journal Nature
According to Reuters, the study’s lead author, paleontologist Giovanni Bianucci of the University of Pisa in Italy, stated: “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.”
According to estimates, Perucetus had a minimum mass of 85 tonnes and an average mass of 180 tonnes. Despite the fact that the largest known blue whale weighed around 190 tonnes, it was longer than Perucetus, reaching 110 feet (33.5 meters). In comparison, Argentinosaurus, a plant-eating dinosaur that lived around 95 million years ago in Argentina and was thought to be the largest gigantic dinosaur, according to research released in May, was significantly smaller, weighing an estimated 76 tonnes.
Where did the colossus whale turn up?
The incomplete skeleton was discovered in southern Peru’s coastal desert. According to Reuters, the region is rich in whale fossils. Scientists have so far discovered 13 vertebrae, four ribs, and one hip bone from Perucetus colossus. The bones were discovered to be abnormally massive, dense, and compressed. The skeletal mass alone is estimated to be between five and eight tonnes, more than twice that of the blue whale.
Researchers have failed to discover its cranium or tooth remnants. This means we have no idea about its diet or lifestyle. Bianucci suggests that it is possible that this creature was “herbivorous like the sirenians, but this would be the only case among cetaceans. Perhaps it fed on small mollusks and crustaceans in sandy bottoms like the extant gray whale. Or it could have been a scavenger on vertebrate carcasses, similar to some extant large-body sharks.”
