Google Scholar leads to me to new science articles

I just discovered Google Scholar as a good search tool. I often find that search engines like GEOREF and Web of Science don’t include some journals that contain frequent articles in the field of vertebrate paleontology. GEOREF focuses on geology and Web of Science focuses on all aspects of science, certain journals don’t make it into their databases. Google Scholar seems to link searches directly with the articles themselves, and offer a competitive search tool. It even has the number of times the article was cited by other articles, which is familiar to uses of Web of Science. After a few searches, realized I had neglected some recent articles published earlier this year. First is an article published in the April issue of the Journal of Morphology by Maureen Kearney, Jessica Anderson Maisano, and Timothy Rowe on the cranial anatomy of a fossil amphisbaenian from the Brule Formation. What I found so remarkable about the article was the ability of using high-resolution X-ray computed tomography to basically isolate various elements of the skull, and model them in the computer without having to take apart the complete skull. Even the little ear bones were successfully isolated using this approach. Truly amazing stuff!

Return from the field

Spending time in the field collecting fossils from the Paleocene and Eocene strata of western Colorado has left me without any recent entries in my blog. I am excited by the discoveries we made this summer and will be returning in July. The beds we collected from represent a remarkable period of time between 60 to 55 million years ago. During this time the physical world was undergoing rapid changes in climate and geography, while the animals on land and in the oceans underwent a significant modernization. Most modern mammals arose during this interval of time. How these changes occurred during such a short period of time is one of the many questions I am addressing with my research. Based on the fossils discovered this summer, the area is unlike other terrestral sections that preserve this time interval and may offer an unique perspective on the Paleocene-Eocene transition. I will be presenting the results of this work in the fall at the Soceity of Vertebrate Paleontology annual meetings in Arizona.
