Snail Fossil Discovered: 100 million year old snail family found hidden in ‘glue’, mother already knew the end

Fossils of land-dwelling snails are usually preserved in shells or imprints, while their body remains are rarely preserved. Now scientists have found the remains of a snail from about 100 million years ago. Interestingly, the female to which these snails belong may have given birth to a baby shortly before fossilization. That too is preserved in the same amber in which the female snail has been found. Dr. Adrian Johum of the Senckenberg Research Institute and Natural History Museum, Frankfurt and the Natural History Museum Bjarmind Bern says that the snail’s body and shell have been found inside Cretaceous amber in Myanmar, which is quite well preserved. Some time before this his child must have been born and that too has been found preserved in Amber. Together with scientists from China and Japan, Adrian studied amber with the help of high-resolution photography and micro-computer tomography images.

The study found that the snail’s shell is 1.1 cm long. Five children have also been found in this. Amber is a tree gum that hardens over time. The fossils coming in it have also been found preserved. Adrian has told that seeing the gum coming, the female snail understood what was about to happen. This is understandable by seeing the position ‘alert’ of his hands. They say that these creatures must have eaten rotten leaves.

Why babies instead of eggs?
These babies were found to be smaller than the ones hatched from eggs. Their number is also less. Researchers believe that instead of laying eggs, it may have been necessary to produce a small number of children so that they could be protected from predatory creatures. According to the study, fossils found from northern Myanmar provide important evidence about the behavior and ecology of this creature that lived 100 million years ago. On the basis of these, the structure of animals can also be understood and it can also be known that there used to be viviparous snails.
