Revision and re-evaluation of the Early Jurassic dinosaurian
These data strongly suggest that the DNA is original, but without sequence data, it is impossible to confirm that the DNA is dinosaurian
Unlike their dinosaurian

The authors conclude: "Our discovery, and subsequent report, of these sauropod dinosaur remains from Antarctica improves our current knowledge of the dinosaurian

What's particularly interesting is that it retains many of the primitive dinosaurian
features that are absent in modern birds, but it has wing and shoulder [adaptations] that are very avian," says Chiappe.
While conducting virtual reality research, players must maneuver the creature through a variety of different activities in order to solve dinosaurian
Of particular significance is the fossilized skeletal material attributed to early lizard, crocodilian, and dinosaurian
Birds would have inherited feathers from their dinosaurian
ancestors and later used them for flight.
