They found the maxilla to be a reliable reference when inferring the shape of the premaxilla and overall snout. For instance, most Asian species have elongated snouts based on the maxilla (namely velociraptorines), indicating a selective feeding in Velociraptor and relatives, such as picking up small, fast prey. In contrast, most North American ...
Utahraptor was one of, if not the largest and heaviest of all dromaeosaurids, with the largest assigned specimen BYUVP 15465 having a femoral length of 56.5–60 cm (22.2–23.6 in). [8] [9] Utahraptor is estimated to have reached 6–7 metres (20–23 ft) in length and somewhat less than 500 kg (1,100 lb), comparable in weight to a polar bear.
The 5-ton apex-predator measuring 3 stories from nose to tail was found eviscerated its prey with sharp, curved claws. "Death shadow" fossils of largest raptor dinosaur unearthed in Argentina Skip ...
Giant 20-foot-long raptor dinosaurs once roamed Australia, according to a new study that could rewrite the evolutionary history and hierarchy of predators on the continent. The research, published ...
The osprey, a single species found worldwide that specializes in catching fish and builds large stick nests. Owls are variable-sized, typically night-specialized hunting birds. They fly almost silently due to their special feather structure that reduces turbulence. They have particularly acute hearing and nocturnal eyesight.
The bald eagle has sometimes been considered the largest true raptor in North America. The only larger species of raptor-like bird is the California condor (Gymnogyps californianus), a New World vulture which today is not generally considered a taxonomic ally of true accipitrids. [18]
