The new species also sits deep within the evolutionary tree of theropods, much more so than coelurosaurs
, meaning that the species that stem from Sciurumimus are likely to have similar characteristics.
Many paleontologists speculate that modern-day birds emerged from Coelurosaur rootstock, an idea bolstered by recent finds in China of early Cretaceous fossils of what were apparently feathered Coelurosaurs (SN: 4/28/01, p.
Kirkland describes the new predator, a yet-unnamed type of Coelurosaur, as "the coyote of the Cretaceous.
9in) to 80cm in length, belong to dinosaur types including tyrannosaurs, coelurosaurs
From his studies of the earliest known bird, Archaeopteryx, Ostrom recognized various anatomical similarities between the ancient bird and a group of bipedal dinosaurs called coelurosaurs.
Although many paleontologists at the time viewed dinosaurs as clumsy and cold-blooded, Ostrom theorized that coelurosaurs and other theropod dinosaurs were agile, warm-blooded predators.
