Signs of fossilized sting indicate that there could be a dramatic struggle between a giant terrorist bird and more massive crocodiles for about 12 million years.
Phaorushacids, known as “terrorist birds”, was the predator of the prey in ancient ecosystems in South America. While these eaten animals, which no flights had little, had a little fear on the ground, a new study, published on Tuesday (July 22) in the magazine Biology messagesIt indicates that she was not necessarily safe around water.
The researchers analyzed the signs of teeth on the leg bone from anyone The largest terrorist bird ever Its height is estimated at more than 9 feet (2.7 meters) – It was discovered on the La Venta Fossil site in Colombia. The team concluded that Kayman was 15 feet long (4.7 meters) was responsible for the signs.
“We have learned that terrorist birds can also be broadcasting [upon] Even being an APEX predator has risks, “the main author of the study Andre’s linkHe told the world of excavation and biologist at the University of Andes Mountains in Colombia, in an email.
The study does not exclude the possibility that the terrorist bird simply died near the body of water and was then chewed by Kayman, which makes it a state of wiping instead of hunting.

The researchers revealed for the first time the terrorist excavations in a study Posted last year. The authors of the study at the time said that they are suspected that crocodiles were killed, but they have not yet published an analysis of the four tooth signs on the bone.
For the new study, the researchers evaluated the bite mark by creating detailed 3D images of the excavation. Bone signs did not have any signs of recovery, while the size and shape of the signs were consistent with those that were delivered by Kayman, which ranged from 15.1 to 15.8 feet (4.6 to 4.8 m), according to the study.
The team assumed that the biggest types of Kayman in La Venta, Purussaurus NewnsisIt was behind the bite. However, the responsible individual will be a subcontinent, and it has not yet been cultivated. Live science link said P. Neredsis It can rise to about 33 feet (10 meters). “It was a huge animal!” He said.
Without direct proof of the eating of the belts of terrorist birds, the results are a description of stories of the predation of a water summit that feeds on the predator of the Earth’s summit during the midst of the Myosen (23 million to 5 million years ago).
“In my opinion, this study contributes to understanding the diet PurussaurusThe scene of fear near the water bodies [at] La Venta through Middle Misen and complex environmental interactions in Protamazonian ecosystems from [tropical] south america.
