Latenivenatrix

名字的意思： “hiding huntress”1

Latenivenatrix was a large, bird-like dinosaur that lived in what is now Canada. It was one of the biggest troodontids ever found, and it probably ate both plants and meat. Scientists are still debating whether it was really its own species or just a different name for another dinosaur called Stenonychosaurus.1 4

趣味知識

Latenivenatrix is the largest known troodontid, reaching up to 3.5 meters (11.5 feet) in length.1

Its name means 'hiding huntress' in Latin, because it was a stealthy predator.1

The first fossil of Latenivenatrix was found in 1968 by Irene Vanderloh in Alberta, Canada.1

Some scientists think Latenivenatrix might actually be the same species as Stenonychosaurus, not a separate dinosaur.1

Latenivenatrix had a special pelvis with a pubis bone that was tilted backward at a 17-degree angle.1
