Is the Liopleurodon still alive?
Liopleurodon Went Extinct by the Start of the Cretaceous Period. As deadly as they were, pliosaurs like Liopleurodon were no match for the relentless progress of evolution.
What was the largest marine dinosaur?
One of the biggest specimens ever found was identified as Mosasaurus hoffmanni and was estimated to be about 56 feet (17 meters) long in life, according to a 2014 study published in the journal Proceedings of the Zoological Institute RAS. Not all mosasaurs were giants though.
Who discovered Pliosaurus?
collector Kevan Sheehan
The 155-million-year-old fossil was discovered by collector Kevan Sheehan in 2003 in cliffs near Weymouth. Named in his honour as Pliosaurus kevani, in the online journal PLoS One, Mr Shehan said it was a “great day for Kevs around the world”. Two pliosaurs unearthed in Wiltshire have also been named as new species.
