Research: a medical scanner helps unlock the mysteries of a prehistoric sea reptile –



Almost a meter long canopy of fossil-sea ichthyosaur canopies discovered in the peasant area over 60 years of age.

Finally, with computerized tomography (CT) scanning technology, the research provides new information that includes rarely conserved brain details.

He discovered almost 200 million years of fossil in 1955 in Fell Mill Farm in Warwickshire, never before investigated.

Now, thanks to data from CT tests, the research team fully reconstructs 3D skulls. For the first time, a digital reconstruction of a great cranium and mandrel has been carried out for research purposes and for public.

Although in the United Kingdom there are fossil ichtyosaur fossils, this species is particularly important and it is unusual because it has been preserved in three dimensions and rarely has bone bones.

In 2014, the Thinktank Science Museum, Birmingham, Dean Lomax, paleontologist, Manchester University and Nigel Larkin completed their first skeleton and skeleton.

Dean, the lead author and one of the world's leading ichthyosaur experts, said: "For the first time, I saw this species that I had mixed with for excellent conservation.

Ictyosaurs (Early Jurassic) in this age usually "Pancake & # 39; They are therefore squished, so the original structure of the skull is not maintained or distorted or damaged. Therefore, skulls and fragments of the skeleton of the ichthyosaurus in this age-conserved age, and without fragility, is something special. "

Ichthyosaurus communis was identified as a common species called ichthyosaur, but after closer examination, Dean convinced that it was a strange species. Based on the different features of the Skull, he identified it as an example of an ichthyosaur called Protoxicthosaurus prostaxalis. Two more than two skulls twice a day ProtoxicthyosaurusIt is the main species known for this species.

Nigel Larkin co-authored: "Initially, the project's goal was to clean and conserve cranium, and was partially disassembled and reconsidered, ready to redistribute the Thinktank Museum, but soon we realized that the individual skeletal skulls were very well maintained in three dimensions, we saw any ichthyosaur skull, and they would also take care of CT scans to digitally extract shape and see inside details, which can not be missed "

The skull is not quite complete, but the bones of the braincases are rarely stored in the herbivores. To unblock the information contained in Skull, some of these bones had a micro-CT Scan at the University of Cambridge in 2015, an expert paleontologist and co-author, from the College of London (UCL), Laura Porro University.

Fossils only maintain left brain bones; However, using CT, these elements were digitally mirrored and printed in 3D printed life to form a braincase. In the end, the entire skull was scanned at the Royal Veterinary College (RVC) for CT scanners and other large-scale animals.

Porro Dr added: "It allows us to look inside the fossilized CT scans – in this case, the cranial bones originally found long channels inside the blood vessels and nerves. Scans also revealed the history of grain in the 1950's since its discovery. Gypsum and clay reconstructed areas There were some, and a bone was so molded that scanning only made the part a false one. Finally, it reconstructs the 3D skulls digitally. This is a tough (and dangerous) fossil bony origin, fragile and very heavy, and we can also make 3D reconstruction to be available for scientists and education. "

Modern technologies, such as the use of medical scanners, have allowed paleontologists to study and describe fossils.

Dean added: "It takes more than half a century to investigate and describe this type of tincture, but it is worth the wait. Our research does not show exciting information on the internal craniality of this animal, but our findings help paleontologists to explore their relationship with other ichthyosaurs ".
