New discovery from fossils of two mammoths

Using high-tech tomography techniques for fossils of two small mammoths taken from the permafrost of Siberia revealed more new information.

Accordingly, both of them are female elephants, not one of which is male elephants as originally thought. In addition, this technique also shows a big difference in bone structure between them.

'Previously, a lot of research on mammoths was done based on dental surgery, based on what we can see from the teeth. But now, we can analyze on many parts of the mammoth baby including skin, fat, muscle, bone . ' , Dr. Ethan Shirley from Michigan University spoke at Hiep's annual meeting. Vertebrate paleontology

Two mammoth fossils named Lyuba and Khroma were found in 2007 and 2009. Scientists say Lyuba dates to about 42,000 years while Khroma was discovered under old sediments.

Previous research results confirmed that Lyuba was a female elephant, it suffocated in thick mud after being trapped. Khroma was originally identified as a male. And the cause of its death is an infection caused by anthrax.

However, recent research concludes some other causes. Besides, the CT scan technique of Khroma's genital tract also revealed an interesting thing, in stark contrast to the previous information. Accordingly, this fossil is also a female elephant.

In addition, when analyzing the skeletons of Lyuba and Khroma, the team also found that although both are of the same species, there is a big difference in bone structure between them. Lyuba's forelegs had a longer rate than Khroma, and while Khroma had bone tips in the position where the ivory pair would grow, Lyuba did not.

'In any case, these traits give us a clearer picture of the many types of variants that exist in mammoth creatures , ' Shirley said. 'This is the result of the natural selection process that creates evolutionary changes,' he added.
