An extremely rare , and extremely weird - take care , fogey dating to or so half a billion years ago has been unearth in China by an outside team of research worker . The specimen belongs to a strange , balloon - like animal that dwelled in Cambrian seas some 520 million twelvemonth ago , and is helping us understand more about the variety of life in Earth ’s ancient oceans .
As account inScientific Reports , the fossil was collected a few long time back from the Heilinpu Formation in the Yunnan Province of southern China . Thousands of various fossils have been gathered from ancient rocks in this area over the preceding 30 year , include more than 30 different species with surpassing preservation . remnant of their gentle anatomy could also be seen in some specimens , such as their eyes , guts and brains . Nonetheless , the unexampled specimen had never been documented before , play up its rarity .
The animal lived during theCambrian Period , a time when an unbelievable array of life began to emerge on Earth , including the majority of the major groups of animals . Because these various life forms appeared over a comparatively brusque fourth dimension point , the result is often name to as the “ Welsh Explosion , ” but the scale leaf wasprobably enlarged . This is because strong - bodied animals set about to proliferate during this meter , which are more potential to leave behind ossified clay for us to find than their soft - embodied precursors .

To analyse the morphology of the specimen , the researchers created3D imagesusing X - light beam Computed Tomography . Although the animal now somewhat resembles a squished birds nest , originally it was balloon - work and adorned with an taboo skeleton of triangular spines . These animals were stalkless , or firm , so the backbone would have served as a United States Department of Defense mechanism to prevent them from being eaten by piranha .

The dodo ’s striking nest - like appearance dish up as inhalation for its name , Nidelric pugio , after the Latin wordNidus , meaning fowl ’s nest . The latter part of the password is derived from an Old English name , Aedelic , which is a source for the name Aldridge , in honor of the late Professor Richard Aldridge who was an expert in Cambrian fogy from the area where the new species was discovered .
The animate being was in all probability achancelloriid , a bizarre group of spiny , base - shaped animals that does not come along to be the ancestor of any live species today . The fossilization process flattens these bloated animals , which is why they incline to resemble a spiky bird ’s nest . Researchers are often forced to puzzle out with very fragmented fossils due to corroding over time , but this new specimen was exceptionally well - preserved .
“ With this specimen we can see how all the dissimilar parts of the skeletal system stuck together , ” PhD student Tom Hearing explains in anews expiration . “ It tells us much about how early animals functioned , how they might have interacted with other animals , and how they might have protected themselves from predators . ”
