A closer look at a dinosaur bone found in the Garden Park area shows some interesting details on the end of the bone. The holes in the dinosaur bone shown in figure 1 used to be tube-like structures called Haversian canals. Haversian canals are branching channels where the blood vessels and nerve fibers are carried through the bone.
Figure 1. As shown in this photo, the Haversian canals have dried out, leaving hollow holes throughout the bone. Photo by K. Lahmers. S.W. Veatch specimen.
Figure 2. This Jurassic dinosaur bone was once a rather large, live, and active dinosaur that was part of a prehistoric ecosystem that included streams and ponds. Photo by K. Lahmers. S.W. Veatch specimen.
This large dinosaur bone(fugue 2)—petrified in what became known as the Morrison Formation—quietly waited to be discovered and studied by the Colorado Springs Mineralogical Society(CSMS) Pebble Pups and Junior members. This paper is the result of a CSMS Pebble Pup and Junior member study group to: 1) look some of the structures of a dinosaur bone and, 2) to learn how to take pictures of paleontological specimens. We accomplished our mission in the 45-minute monthly class. More exciting studies and papers are planned.
