Lemmysuchus was a sea-going member of an extinct group called teleosaurs, common during the Jurassic Period but only distantly related to today’s crocodiles.Sea crocodiles spent large amounts of time in the water, they probably clambered back onto land to lay eggs, researchers believe.The specimen was recently studied by Michela Johnson, a current palaeontology PhD student at the University of Edinburgh, who realised it had been wrongly classified.“Following careful anatomical comparison, and by referring to the main specimen held at the Natural History Museum, we could see that most of the previous finds were actually from relatives of Lemmysuchus rather than the species itself, and we were able to assign a new name,” added Miss Johnson.Born Ian Kilmister in 1945 in Stoke-in-Trent, it was said Lemmy gained his nickname after constantly pestered people to “lemme a fiver”. Its skull measured just over a metre and large, blunt teeth perfect for crushing bones and shells.A fossil skeleton of one of the creatures was dug up in a clay pit near Peterborough in 1909 and then housed at London’s Natural History Museum (NHM), where it has remained largely unstudied ever since.But a recent reexamination led experts to believe that the creature stood apart from the other sea crocodiles of its time, and so deserved a new name.NHM Curator Lorna Steele said: “I’ve always been into heavy rock, and Motorhead are one of my favourite bands and since Lemmy died I have been keen to name something after him.“I had found a small crocodile in Morocco and thought that would have to do, but then this one emerged and I thought ‘Oh My God!’ this is the nastiest, meanest, biggest sea-crocodile there was. So it was perfect.“Sea crocs are extinct now, but they were once a massive group of their time and were dominant in the Middle Jurassic. You wouldn’t have wanted to come across one. They were far bigger than today’s crocodiles. These things were massive, with armoured plates on their back and belly.“Although Lemmy passed away at the end of 2015, we’d like to think that he would have raised a glass to Lemmysuchus, one of the nastiest sea creatures to have ever inhabited the Earth.” Lemmysuchus had a huge jaw and teeth which could crush the skulls of sea turtles Credit:Mark Witton and Trustees of the NHM, London ‘Lemmysuchus’ – which translates as Lemmy’s Crocodile – was a giant 19ft (5.8m) predator, which was covered in thick armour and was one of the most deadly marine creatures of its day, crunching down sea turtles with a snap of its giant jaws.Lemmy, who died aged 70, in December 2015, was the founder, singer and bassist of Motorhead for 40 years, a band which took pride in its reputation for playing and living louder, faster and harder than any other group.Likewise, his nightmare-inducing namesake, was bigger, faster and scarier than most sea creatures, terrorising the shallow coastal waters around the UK more than 165 million years ago.
