I was very fortunate to win the christmas acution lot H that praefectus put up. This lot was composed of a spinosaur tooth and enchodus fang and partial jaw. They are really pretty fossils that will have a good home in my collection. The enchodus was in matrix, and I cleaned up a little more around the fossil, so now I hav e additional bone fragments that I would like to ask for help in understanding. On the lower right is a piece of a vertebrae?. In the lower left ther is another segment of jaw with part of a root for a tooth, What if anything can be made of the larger white blobs? Also on the lower side of the main jaw fragment are 4 triangles they are not teeth but what are they?
