Edinburgh, Aug 26 (): The researchers have uncovered evidence of biggest fish ever lived in prehistoric period was 16.5 metres long called Leedsichthys.
The Leedsichthys, which lived in the Middle Jurassic period around 165 million years ago, was a huge bony, plankton-eating fish. The skeletal remains of the fish have been uncovered over the years but haven’t preserved well. The skeletal remains were uncovered off the coasts of France and Mexico. The skeleton was mostly made of cartilage and does not fossilise easily. In Whittlesea near Peterborough the researchers unearthed an almost complete skeleton of a Leedsichthys several years ago.
This creature could grow to eight or nine metres in 20 years and reach 16.5 metres in length in 38 years.
Jeff Liston, Professor who led the research said, “the giant plankton-feeders we know to live in today’s oceans are among the largest living vertebrate animals alive.” He added, “What we didn’t have any clear idea of, was how large this large fish really was: its skeleton preserves poorly, it is often just isolated fragments, so previous size estimates were largely historical arm-waving exercises.”
He also said “this fish was a pioneer for the ecological niche filled today by mammals, like blue whales, and cartilaginous fish, such as manta rays, basking sharks and whale sharks.”
