GLACIAL MORAINES IN THE VICINITY OF ESTES PARK, COLORADO

Abstract

Brown. My son Levi has beautifully restored it. It lay on the side of a steep slope, part of one side washed down the hill. However, when they were restored, very little was missing. It is the best specimen my parties found in the four years we collected there. It is 41/2 feet long, and as far as I know, equalled only by the type in the American Museum, New York, where they have the entire skeleton. I have described these dinosaurs in my recent book, Hunting Dinosaurs in the Red Deer River, Alberta, and need not go into details here. In addition to the dinosaurs collected, I secured a large collection of scattered bones that will be of value as hand specimens to illustrate the wonderful fauna of the Pierre age. We secured some fine turtles. Two, in fact, have nearly perfect shells. One, Lambe's Boremys pluchra, a new species, Levi found in 1913. The other is evidently new, and is the only one I have found in the Belly River Series, either in Montana or Canada, where the ribs are not co6ssified to the margin. It resembles somewhat the sea tortoises of the Niobrara chalk of Kansas. Then we have a beautifully sculptured plastron of a new species of Aspiderites, a form that was not covered with horny scutes, half the plastron of a large Adocus that must have been three feet long in life. This shows the marks of very strong horn plates.
