My Previous Projects

 

        This is only a listing of the major projects I have worked on outside of classes. The projects are summed up in a couple of lines and a few images to show what was done. This is not meant to be the all encompassing project, just a little snippet of it. Any questions on the projects feel free to email me (email on bottom of page).

 

2001 - 2002

 

Lehane, J.R.  and Over, D.J. 2002. Canid and rodent scavenging on Pleistocene cave bear: Geological Society of America Abstracts with Programs 34 (6); p.150

 

        This was the first real project that I did. It was for my invertebrate paleontology class but since my professor knew how much I was into vertebrates he let me work on this instead. The goal of the project was to show that scavenging occurred to Pleistocene cave bear bones by comparing it to teeth marks made on pig bones by mice and a dog.

2002 - 2003

 

Young, R.A. 2003. Recent and long-term sedimentation and erosion along the Genesee River floodplain in Livingston and Monroe Counties, NY. Funded by the US Army Corps of Engineers. pp. 1-40

 

        This project was funded through the US Army Corps of Engineers and directed by Dr. Young. The purpose was to find different erosion rates along the Genesee River from Mount Morris to Rochester, NY and to discover a cause for faster erosion and possibly a solution. This required several different aspects with the first part including a fellow geology student, Jeff Mortier. The two of us canoed the river between these two cities. All the while mapping the edge of the river with GPS points, measuring the width with a laser distancing tool, and documenting the location with digital photographs. Then using ArcGIS 8.0, I rectified aerial photographs of the river from different years, traced the rivers, and finally included the current river location using the GPS positions.

  The fastest growing meander of the Genesee River. I created the map using

  aerial photographs from the years listed and overlying them using "permanent

  structures" as anchor points like roads and buildings. Then the river was traced

  over with the black line representing the most recent location.

                            river is not even near where it is on the map.

        So essentially my thesis project involved rebuilding a skull attributed to the dinosaur Shuvosaurus inexpectatus. The skull first needed to be taken apart, cleaned and undistorted. These pieces then needed to be cast and their mirror images needed to be created since only 1/2 the skull remained. Then some of the missing pieces needed to be created using closely related animals as a template.
