96 years of life. Colbert's name for this 225 million year old agile bipedal predator translates to "Southern Cross Lizard" with the specific epithet being in honor of Brazilian paleontologist Llewellyn Ivor Price, who had actually collected the fossil. The fossil, as stated, is made up of quite a good portion of the post-cranial skeleton as well as the mandible. Hindlimbs, the pelvic girdle, and the vertebral column are nearly complete; however, the feet and forelimbs, ribs and cranial elements other than the mandible are lacking. All told, animals have been named on far less and the bones present indicate a predator that, at about 66lbs (30kg), 31in (80cm) tall, and 7.4ft (2.3m) long, was about the weight of the average Labrador Retriever but just a tad taller (and obviously longer). The remains that have been discovered and the primitive age of this dinosaur, however, have led to some educated guesses pertaining to the make up of the missing skeletal elements. Chief amongst these are depictions of the hands and feet of Staurikosaurus as five fingered and toed basal appendages. The running speed of Staurikosaurus, despite the primitive foot and pelvic girdle, is considered to be fairly quick given the structure of the legs. The long tail consisting of approximately 40 caudal vertebrae would have aided the quick little dinosaur in maintaining its balance at its higher speeds.
