This hundred million year old crab is perfectly preserved in amber

Over 100 million years ago, dinosaurs traveled the earth while a baby crab migrated ashore. Unfortunately, this animal got stuck in the resin and died. The substance later fossilized and amber preserved not only body parts from cancer, but also soft tissues such as tentacles and even bulging eyes.

The amazing specimen is actually the most complete cancer ever discovered. ancient cancer scientists Cretapsara athanataHe was baptized and raised in northern Myanmar. The science progress According to a study published in a scientific journal, fossilized resin was purchased from local miners in 2015 by researchers at the Longyin Amber Museum in China, but it has not been studied so far.

Not a single hair is missing from the body, which is great – said Javier Luque, a postdoctoral researcher in Harvard University’s Department of Biology and Evolutionary Biology, ZME ScienceTo the online science portal, one of the world’s leading scientists in the field of cancer development. ‚ÄúSeeing the amber, I did not understand what the resin crab was doing, because it is a very strange and incomprehensible phenomenon.

Lida Xing, a specialist and staff at China University, used CT scans to reconstruct a 3D model of the ancient cancer, allowing them to study the sample down to the smallest detail, including the fine hair covering her body.
The 100-million-year-old specimen was very similar to a modern crab, but given its tiny size (only 5 millimeters) it could only be a few days old. The oldest crustaceans discovered so far date from the Jurassic period, but earlier crab stones have been shown to be incomplete and composed largely of pieces of claws.

However, the new specimen is 25 to 50 million years older than the previous cancer-like fossils and is a perfect match for the molecular reconstruction of the “cancer tree of life.”

Molecular DNA analyzes predicted that terrestrial crabs separated from their marine ancestors more than 125 million years ago.

Thus, this remarkable current specimen can bridge the gap between theoretical predictions and actual fossil records. Experts say this could also mean that crabs took their first steps on Earth much earlier than science had until now believed.
However, it is not yet known whether Cretapsara athanata lived as a terrestrial species or not, but it appears that it may not have fully adapted to terrestrial life due to its incomplete lungs. Scientists believe this ancient crab may have enjoyed in fresh or perhaps salt water, and its favorite habitats may have included puddles formed on the forest soil.
