Rare Sea Creature Found Trapped In Amber of 99 Million Years Old


A fascinating and extremely rare sea creature was spotted in amber which dates back to 99 million years ago. The fossil, which has the size of a fingernail, was observed in a large piece of amber. At least 40 other organisms were also present, and it is known that they used to live on land or sea during the mid-Cretaceous era.

The discovery is quite spectacular since the ammonite, which is thought to be related to modern squids, is one of the rare cases in which sea life was kept in amber produced by land trees. Such fossils are quite crucial since the excellent state allows researchers to learn more information about the creatures which were captured and how they evolved as time passed.

By using advanced X-ray micro-computed tomography, the researchers obtained high-quality 3D images which infer that the fossil was a juvenile Puzosia, which is known to be a subspecies of ammonites which feature a whorled shall. An obvious question appears: how a mollusk precursor managed to be caught in tree resin among land creatures like spiders, wasps, and cockroaches?

It is thought that the resin was released by a conifer tree which could have been encountered in an area close to the coastline. As the resin poured out from the tree due to gravity some creatures were caught.

At one point, the resin ended up on the beach, where came into contact with marine organisms. The lack of soft tissue in the ammonite shell and other shells found in the amber suggests that the creature were already dead when the resin covered the organisms.

According to the authors of the study, this fossil plays an essential role in the establishment of what used to be present-day Myanmar. It is crucial to keep in mind the fact that dating amber is quite complicated, but the researchers are confident about the current results. The study was published in a scientific journal.
