A 2-mm crab fossil from a piece of amber found in China has updated knowledge of when land crabs first appeared. The nearly 100-million-year-old fossil that filled the evolutionary gap showed that land crabs emerged between 100 and 125 million years ago.
Since amber patterns were able to contain living things while forming millions of years ago, they provide us with a lot of information about what animals looked like in the distant past and evolution in general. A new piece presents the best preserved of an ancient crab species.
An amber piece found in China excited scientists with the 2 mm crab fossil it contained. The best preserved example of its kind The crabs filled the unidentified millions of years gap in the evolution of crabs.
A 100-million-year-old crab fossil trapped in amber:
Researchers at the University of Alberta examining the fossil are about the crab that filled the evolutionary gap. “This crab tells us an interesting story about the cycle that crabs go through. Crab evolution is a hot topic; because throughout history Many crab-like species evolved independently of one another.”
Until now, the time when crabs left the seas as land crabs and later freshwater crabs had been dated to between 50 and 70 million years ago. These researchers, who examine the crab and process the molecular records created by collecting DNA and RNA differences and similarities, are the ones who distinguish between land and sea. 100 to 125 million years found out that it had happened before.
