Despite a land area of just 148 square miles (384 km2), the Isle of Wight, an island off England, is one of the richest dinosaur localities in Europe. In fact, over 20 species of dinosaur have been found there from the early

Research led by paleontologists at the University of Southampton has identified the remains of one of Europe’s largest ever land-based hunters: a dinosaur that measured over 10m long and lived around 125 million years ago.

Several prehistoric bones, uncovered on the Isle of Wight, on the south coast of England, and housed at Dinosaur Isle Museum in Sandown, belonged to a type of two-legged, crocodile-faced predatory dinosaur known as spinosaurids. Dubbed the ‘White Rock spinosaurid’ – after the geological layer in which it was found – it was a predator of impressive proportions.

“This was a huge animal, exceeding 10 m in length and probably several tonnes in weight. Judging from some of the dimensions, it appears to represent one of the largest predatory dinosaur ever found in Europe – maybe even the biggest yet known,” said PhD student Chris Barker, who led the study. “It’s a shame it’s only known from a small amount of material, but these are enough to show it was an immense creature.”

The discovery follows previous work on spinosaurids by the University of Southampton team, which published a study on the discovery of two new species in 2021.

The bones of the ‘White Rock spinosaurid’, which include huge pelvic and tail vertebrae, amongst other pieces, were discovered near Compton Chine, on the southwest coast of the Isle of Wight. The Cretaceous rocks are famous for their dinosaurs, but little appreciated is the fact that the Island’s fossil record preserves dinosaurs from more than one section of history – and some of those sections, even today, are poorly known.

“Unusually, this specimen eroded out of the Vectis Formation, which is notoriously poor in dinosaur fossils,” said corresponding author Dr. Neil Gostling, who…
