Motörhead founder, singer and bassist Ian "Lemmy" Kilmister, who died on December 28, 2015, famously sang, "I don't want to live forever", in the band's signature song, "Ace of Spades". Roughly translated, it means "Lemmy's blunt-toothed crocodile".
The monster that terrorised coastal waters around the United Kingdom more than 145 million years ago had a skull measuring just over a metre and large, blunt teeth ideal for crushing bones and turtle shells.
Ms Johnson realised it had been incorrectly classified and required a new scientific name, with the Lemmy inspiration coming from the Natural History Museum's Lorna Steel.
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.

While the story was no longer on the website's homepage, it would remain on the internet, he said. He called on PinkNews to immediately withdraw the " misjudged " article and apologize.
"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", Dr Steel said.
Lemmysuchus was about 5.8 metres long and had a skull longer than a metre - similar to a modern-day saltwater crocodile to which it is only distantly related. According to Inverse, Lemmysuchus obtusidens lived 164 million years ago, was 19 feet long, and would have fucking loved Jack and Cokes, if Jack and Cokes had existed in the Middle Jurassic Period.
"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".
The findings were published online August 7 in the Zoological Journal of the Linnean Society.
