Dinosaur Species Extinction
Montana Paleontologists Compile Growth Series Analyses Adversely Affecting Dinosaur Species Diversity
Holly Brown
ABSTRACT
The purpose of this paper is to report the findings of paleontologists Horner, Scanella, Goodwin and others regarding their study of growth series analysis in dinosaurs. They have provided evidence that what once was considered multiple different species of dinosaurs are actually varying stages of development in one genus. Utilizing the extensive fossil record at hand for Ceratopsians and Pachycephalosaurs they microscopically examined the bones looking for levels of bone maturity and metaplastic bone to discern the animals place in the growth series and develop their hypothesis for stages of growth for these dinosaurs. …show more content…

A paper found online reviewing Archibald 's book on the importance of species diversity in ancient ecosystems. Discusses the causes of dinosaur extinction apart from the critical meteor impact that aided in their demise.
