The determination of the survivorship pattern of Albertosaurus sarcophagus and determine the factors making these animals vulnerable to mortality. Analysis of fossil assemblage of 22 individuals of Albertosaurus sarcophagus , a relative of Tyrannosaurus rex. All 22 died at the same time probably, but at different ages due to starvation. Growth lines present in fossilized leg bones were used to determine the age of death of each specimen. No data for very young individuals were obtained and 60% mortaility rates between birth and age too were assumed. Further, the table is extrapolated to 1000 individuals as given : Introduction: There are different types of species that have different anatomy, behavioral patterns, and habitat. Species also differ in their life span. We can track down the life of these different organisms with the help of survivorship table and curve. This table provides a reference to the birth of organisms born at the same time die in each year or unit time.

Question

Radiometric dating and the cranial capacity measurements are back from the paleolab for the specimen your friend at the museum called you about. She calls again to tell you the results. The cranial capacity is 442 cubic centimeters and it dates to 3 million years ago. After having identified the cranial traits present, you can now take this new information and provide, at least, the genus you think it could belong to in order to help your friend. Based on this information, choose from the options below, the category to which you think it most likely belongs.

Radiometric dating and the cranial capacity measurements are back from the paleolab for the specimen you discovered at the site you were excavating in South Africa. Lab results indicate that the cranial capacity is 520 cubic centimeters and it dates to about 1.5 million years ago. After having identified the cranial traits present, you can now take this new information and provide, at least, the genus to which you think it may belong. Based on this information, choose from the options below, the category to which you think it most likely belongs. -Pre-australopith -Premodern Human -Gracile Australopithecine -Early Genus Homo -Robust Australopithecine -Late Genus Homo

Brown et al. and Morwood et al. reported in 2004 that they had found skeletal remains of a previously unknown type of hominin, now dubbed Homo floresiensis, on the Indonesian island of Flores. These hominins were small (approximately 1 m tall) with small braincases (approximately 380 cm3) as compared with other hominins. The remains of H. floresiensis were found alongside handmade stone tools and the remains of dwarf elephants that also inhabited the island, suggesting that H. floresiensis was able both to make tools and to coordinate the hunting of animals much larger than itself. H. floresiensis is estimated to have lived at the site where the remains were found from 700,000 years ago to 60,000 years ago. Which would be the most feasible method of figuring out to which other hominin species H. floresiensis was most closely related? Compare the average body size of H. floresiensis to that of each of the other hominin species. Compare the type of prey hunted by H. floresiensis to that…
