Lived tens of millions of years ago dinosaurs we know surprisingly little about it. However, this does not change the fact that they leave plenty of bone behind to find, study and make informed predictions about them.
Dinosaur fossil from China offers new clues
The most durable and long-lasting remains of dinosaurs today hard bones soft tissue is very difficult to obtain. As a result of this situation mating Understanding more complex behaviors such as But recently Chinaa new from fossil, brings scientists to new knowledge about dinosaurs. Fossiloffers clues as to how dinosaurs defecated and reproduced.
Current BiologyIn an article published in ChinaThe research team, who studied the fossil from, explained that its soft tissue provided rich details about the dinosaur’s back. Additionally, the team identified the opening where the fossil and the dinosaur urinated, defecated, and possibly mated. This singular span, cloaca and it is said to be common in birds, the closest living relatives to dinosaurs today.
Making a statement about the research, the lead author of the study, Dr. Jakob Vinther, “I noticed cloaca a few years ago when I recreated the color patterns of this dinosaur using an extraordinary fossil displayed at the Senckenberg Museum in Germany. It took us a long time to finish because no one bothered comparing the outside of the living animals’ cloacal openings, so it was a largely unexplored area. ” said.
In this case, the dinosaur species in question cloaca one Psittacosaurussuggests that animals had a singular opening for bodily functions and reproduction, but probably did not mate as birds do today. Modern birds, cloacal They mate by pressing their openings against each other, but this was not possible for dinosaurs. This is where the men of the species in their cloaca showing that she has hidden penises.
Unfortunately, in the opening of the fossil, the organs inside were not preserved and this particular animal’s male or female making it impossible to know.
There is still much unknown about how dinosaurs reproduced. This discovery, it is considered as a single data point that represents only one species from a single point in time. As more fossils began to tell a clearer story of how dinosaurs lived, one day what dinosaur mating looked like and different species’thisHe thinks you can have a better idea of how he does it.
