Collection method comments: The collection is composed of approximately 285 specimens, including ~160 vertebrae (disarticulated, except for three articulated series, including one of four cervicals, one of seven caudals, and another of 21 caudals), over 20 rib fragments, ~20 girdle elements, ~30 complete and fragmentary limb bones, ~30 isolated manual and pedal bones, and ~15 cervical half-ring fragments. This material, all of which is prepared, was examined by the first and second authors
via measurements, observations, and photographs. Soviet-Mongolian Paleontological Expedition |
