Over 20 years ago, the BBC’s Walking with Dinosaurs TV documentary series showed a 25-metre long Liopleurodon. This sparked heated debates over the size of this pliosaur as it was thought to have been wildly overestimated and more likely to have only reached an adult size of just over six metres long.

The speculation was set to continue, but now a chance discovery in an Oxfordshire museum has led to University of Portsmouth palaeontologists publishing a paper on a similar species potentially reaching a whopping 14.4 metres - twice the size of a killer whale.

Professor David Martill from the University of Portsmouth’s School of the Environment, Geography and Geosciences, said: “I was a consultant for the BBC’s pilot programme ‘Cruel Sea’ and I hold my hands up - I got the size of Liopleurodon horrendously wrong. I based my calculations on some fragmentary material which suggested a Liopleurodon could grow to a length of 25 metres, but the evidence was scant and it caused a lot of controversy at the time.

“The size estimate on the BBC back in 1999 was overdone, but now we have some evidence that is much more reliable after a serendipitous discovery of four enormous vertebrate.”



Note bait for scale.

1. For most of history, people believed giants existed

It has just been in the last 100 years plus that we have known about dinosaurs. For most of history, the discovery of huge bones seemed to indicate that giants once existed.
A brontosaurus’s leg bone would most plausibly be identified as the leg bone of a human at least 25 feet tall.
Flat Earth and the sun going around the planet were also “facts” that any thinking person would believe until science later explained those misconceptions.
I guess you could also put the spontaneous creation of the Earth by a Supreme Being into this category.
