Livestock Ichthyosaur: 205-Milion-Year-Old Large Sea Creature’s Jaw Bone Has Found: Hello, Everyone Today I am going to share some exciting facts on the Lilstock Ichthyosaur 205-Milion-year-old large sea creature’s jaw bone has found.
Livestock Ichthyosaur: 205-Milion-Year-Old Large Sea Creature’s Jaw Bone Has Found
A jaw bone belonging to a gigantic underwater reptile has identify as belonging to “one of the largest animals ever”.
Found by the fossil collector Paul de la Salle in Lilstock, Somerset, the 205 million-year-old remaining have now analysed by an international team of the palaeontologists.
They are concluding it belonged to a type of the fish-like predatory reptile which is called an ichthyosaur, and its discovery suggesting other fossils found in the UK can belong to even more substantial creatures.
At 26 metres in length, the researchers noting the ichthyosaur was approaching the size of the blue whale that is the most substantial animal to have ever live.
“Initially, the bone just looking like a piece of rock but, after recognising a groove and bone structure, I think it may be a part of a jaw from an ichthyosaur,” says Mr De La Salle.
He makes contact with the ichthyosaur experts Dean Lomax, of the University of Manchester, and Professor Judy Massare, of SUNY College at Brockport, who both expressed an interest in studying the bone.
They compared the fossil which is an incomplete bone called a surangular from the lower part of the animal’s jaw with several other ichthyosaur specimens.
Notably, they look at the bone about a specimen held at the Royal Tyrrell Museum of the Palaeontology in Canada, belonging to a species is known as Shonisaurus sikannien.

“As the specimen is representing only by a large piece of the jaw, it is difficult to provide a size estimate, but by using a simple scaling factor and comparing the same bone in the Lilstock specimen is about 25 percent larger,” says Mr Lomax.
“The other comparisons suggesting the Lilstock ichthyosaur was at least 20 to 25 metres.
“Of course, such estimates are not entirely realistic because of the difference on species. Simple scaling is commonly used to estimate the size, especially when a related material is scarce.”
Measuring 21 metres, Shonisaurus was a real monster and the largest which is known as an ichthyosaur.
However, the palaeontologists are analysing suggesting the bone which is found by Mr De la Salle belonging to a similar animal that was even bigger.
With the help of geologist Dr Ramues Gallois, scientists were able to date bone late Triassic time.
In the paper describe discover in the journal PLOS One, the scientists also suggested the new bone could be a sign that prehistoric Britain was home to many more of these enormous creatures.
Five additional bones discovered around Aust Cliff, Gloucestershire, in the 19th century were previously thought to come from dinosaurs.
The identification of new giant ichthyosaur made Mr Lomax, and his colleagues reappraise those bones.
“One of the Aust’s bones may also an ichthyosaur surangular. It is, through comparison with the Lilstock specimen, it may represent a much larger animal,” said Mr Lomax.
“To verify these findings, we need a complete giant Triassic ichthyosaur from the UK – a lot easier said than done.”
So, these are the points to describing on the Lilstock Ichthyosaur 205-Milion-year-old large sea creature’s jaw bone is found.
