BEYOND THE SKELETON “STAN” BHI 3033
There is a story from Black Hills Institute of Geoligical Research believe after several studies made with Tyrannosaurus-Rex’s specimen found together. It is they believe that “Stan” actually lived his life in a group which was his family. “Stan” hatched from an egg which is also like how a modern bird do. (BHI, 1990) He probably have been cared for his family, who taught him the ways to survive especially hunting for food. Later, he grew up and left his family group and found a mate, a female 30% heavier than himself. “Stan” and his mate fought many battles during their lifetimes. (BBC, 2004) is skeleton along with other rex specimen do show the scars of ancient battles. According to the studies made from the “pathologies” in the bones, researchers theorize that rex scuffled for territory, fought over food and engaged in other behaviours similar to today’s carnivores. (BHI, 1990) 02
Several broken and healed bones found from “Stan’s” pathologies. He had also suffered a broken neck, two vertebrate fused together and a third became immobalized by the extra bone growth during the healing process. (BHI, 1990) His cheeks and on the back of his brain case, through the back skull also show healed injuries from a another T-Rex tooth. The circular hole at the back of his skull is more than one inch diameter where a T-Rex tooth can fits nicely. (BHI, 1990) Incredibly, he survived because of a thin layer bone seated the broken surface. The researchers are not sure of how “Stan” died. Perhaps a disease or old age. At any rate, his mate finally had to leave “Stan” on the sand bar of a stream flowing southeastward to the sea. The spring floods ultimately covered the bones which remained buried for 65 million years. (BBC, 2004)
The display was found by an amature Palaentologist, Stan Sacrison at the Hell Creek Formation, South Dakota, United States. Stan skeleton is 12m long, 4m high and the weight is 8 tonnes. (BHI, 1990) The skull dimension of the fossil is 1.5m long and 1m wide with 58 teeth that probably can reach 30cm long. Stan was a male dinosaur because of the body part called Morphotype. It had a gracile morphotype which was smaller and lighter bones than a female dinosaur that had a robust type of morphotype. (BBC, 2004)

THEROPOD DINOSAUR THE “BEAST-FOOTED” DINOSAUR Theropod Species A carnivorous species. (Pagel, M., 2002) Despite the beast-footed name, Theropod had a bipedal feature. The feature of their feets were related to bird’s character. Since these species of dinosaur had a hollow thin walled bones and quite fragile especially the small ones. (Smith,D., 2005) Theropod mostly had four main fingers on the manus (hands) and three main toew on the pes (foot). Most of them also had sharp recured teeth. (Smith,D., 2005) They were also catogarized as a Saurichian Species. Saurischian vs Ornithischian Saurischian is a Lizard-Hipped or Reptile-Hipped group while Ornithischian is a Bird-Hipped group. (Pagel, M., 2002) Ornithischian species were those 4-legged herbivours like Stegosaurus, the armored dinosaurs. These groups were determine by Harry G. Seeley, a former student of Richard Owen in 1888. (Encyclopedia Britannica, 2019) It was differentiate by the position of three elements which were Ilium, Ischium and pubis. The arrangement when the pubis points down and forward are Saurischians and the ones with pubis that points downward and backward are Ornithischian. (Smith,D., 2005) So, Tyrannosaurus-rex is in Saurischian group species. 09
