Paleontologists discovered the footprints of a 5-meter-long (16.4-foot) trodontid in the Longxiang area of China’s Fujian province.
The Ryusho orbital trace contains 12 bipedal orbitals, which are classified into two forms, distinguished by both size and shape.
The small footprints, approximately 11 cm (4.3 inches) long, belong to the long-known genus Ichno. Velociraptoricnus.
Large footprints up to 36 cm (14.2 inches) long Fujianipus inryangi.
Based on body size, this tracker was over 1.8 m (5.9 ft) tall at the waist, comparable in size to the largest known deinonychosaurids. Austraptor and Utahraptor.
“When you think of raptor dinosaurs, you probably think of the muscular, human-sized, aggressive hunters from the movie Jurassic Park,’ said Anthony Romilio, a paleontologist at the University of Queensland. .
“But these traces were left by a much leaner and smarter group in the family. TroodontidaeIt appeared in the late Jurassic period about 95 million years ago. ”
“This raptor was about 5 meters long and had legs of 1.8 meters, far exceeding the size of the raptors depicted in Jurassic Park. Imagine coming.”
“The footprints were compared to other known bipedal dinosaur footprints found throughout Asia, the Americas, and Europe.”
“We found this type of truck to be unique in shape and very unique,” he said.
“The concept of large troodontids has only recently emerged in paleontology.”
“The bones found in Alaska suggest a trend towards giantism near the ancient Arctic Circle, an area where long winter darkness may have led to less competition for species.”
“But our findings suggest that these raptor giants roamed much farther south and were more widely dispersed.”
“Interestingly, some of our research teams are also working on the world’s smallest dinosaur footprint, a Korean raptor footprint that is just one centimeter long.”
“This shows the amazing size range of raptor dinosaurs and highlights their adaptability and ecological diversity.”
