The smoke of 210 million years ago has broken bones like hyenas – ScienceDaily



Koproliti or fossilized dinosaur-like archosurus Smok wawelski contain many bone fragments. This led researchers at Uppsala University to conclude that this top predator exploited bone and bone marrow bones, often associated with mammals, but rarely with arthrosis.

Most of the predatory dinosaurs used their knife-like teeth to feed their prey but did not usually think that they were many blade crushers. The main exception is visible in big tyrannosaurids, such as Tyrannosaurus Rex, which wandered North America at the end of the dinosaur era. Tyranny surrogates are believed to be osteophorous (voluntary bone burial) based on rich bone bones, bone-marked bones, and their robust teeth often worn.

In a study published in Scientific Reports, Uppsala University researchers were able to connect ten large coprolytes Smok wawelski, the ultimate predator of late Trieste (210 million years) gathered in Poland. This two-way, 5-6-meter long animal lived about 140 million years before North American tyrannosis and had T. rexsimilar to appearance, although it is not entirely clear whether it was a real dinosaur or dinosaur-like predecessor.

Three coprolytes were scanned using synchrotron microtomography. This method has recently been applied to copolytes and acts like a CT scanner at a hospital, with the difference that the energy in the X-rays is much stronger. This allows visualization of internal structures in fossils in three dimensions.

It has been shown that coprolites contain up to 50 percent of animal bones such as large amphibians and juvenile nodules. Several crushed toothed teeth, probably belonging to the coprolite manufacturer itself, were also found in copolytes. This means that the teeth are repeatedly crushed on hard foods (and inadvertently swallowed) and replaced by a new one.

Further evidence of bone cracking behavior can also be found in fossils from the same bony layers in Poland. It includes swollen teeth and fossil-rich bones Smok wawelski, as well as numerous bones that are marked or bitten.

It appears that several anatomical signs related to osteopathy, such as a massive head and a firm body, share S. wawelski and tyrannosaurids, despite being distant relatives and living in the space of 140 million years. It seems that these great predators provide evidence of similar adjustments to feeding that they acquire independently at the beginning and end of the dinosaurs.
