PALEONTOLOGY SENSATION: “T. rex of the Sea” Pliosaur with a Mᴀssive 2-Metre Skull Unearthed from Jurᴀssic Coast Cliffs!

A colossal pliosaur skull—the “Sea-Rex”—has emerged from the crumbling cliffs of England’s Jurᴀssic Coast, delivering one of the most complete and ferocious marine predators ever discovered. Measuring nearly 2 metres (6 ft 5 in) long and boasting 130 razor-sharp teeth, the specimen belonged to a 150-million-year-old apex predator that terrorised Jurᴀssic seas with a bite force far exceeding that of Tyrannosaurus rex.

Spotted in 2022 by fossil hunter Phil Jacobs on the beach at Kimmeridge Bay, Dorset, the skull was painstakingly extracted from the Kimmeridge Clay Formation by collector Steve Etches and his team. Suspended on ropes high on the cliff face, they spent weeks chiselling it free before winching the 1.5-tonne block to safety. The fossil is 95 % complete by surface area—earning a Guinness World Record as the most complete pliosaur skull known.

Dubbed the “T. rex of the Sea,” this giant pliosaur (likely a new species of Pliosaurus) dominated the marine food chain, preying on ichthyosaurs, fish, and even other marine reptiles. Its powerful jaws and crushing bite made it one of the most formidable predators in Earth’s history. The specimen, now on permanent display at The Etches Collection museum, was the star of the BBC documentary Attenborough and the Giant Sea Monster.

Researchers say the find offers unprecedented insights into pliosaur anatomy, growth, and ecology. With its immense size and near-perfect preservation, the “Sea-Rex” proves that Jurᴀssic oceans hosted marine monsters every bit as terrifying as their terrestrial counterparts. The Jurᴀssic Coast has once again surrendered a world-class treasure that rewrites the story of ancient ocean giants.
