Mold Type and number of parts

Giant grey femur, caudal depositionaly crushed, broken in about 6 pieces. Breaks were filled with yellow water putty and then stored on open shelving in collections for decades

Very little matrix left on specimen, surface partially covered in shellac, does not appear to have been consolidated, but many gaps quickly filled with water putty to mechanically lock

Paraloid B-72 in Acetone, Cyanoacrylate (PB-40)

10/31/22 - Specimen was given to J. Alicea to remove old putty and repair. Has been labeled in multiple pieces
12/8/22 - Part of specimen broken to reseat a badly joined break. It has been decided between myself and Pedro (fabricator) to leave the femur in 2 halves to prevent future breaks and make it easier to move and mount.
2/10/23 - Femur now in 2 pieces. Proximal half is w Pedro and should be mounted in its welded frame by now. The distal half is in the lab. It has been infilled and remaining fills of water putty have been painted grey to match. Next, I will jump back on the proximal side to do the last painting and touch ups. Ive been given some more context on the history of the specimen. As I understand it was originally collected by the BLM and wound up at UNM before the museum was open. When the museum opened in the 80s' and the alamosaurus was moved over, it had already been broken. S. Lucas says the femur must have been repaired by the same BLM?/UNM? person who used water putty to repair a bunch of other old specimens. This would put the use of the water putty on this specimen and the preceeding break almost 50 years ago
2/22/23 - All structurally excess water putty removed to clear the joins using a num 4 microjack and aro scribes. all loose fragments and cracks stabilized with B72 and pb40 as I went. a pass with a metal wire brush to try to scrub out the water putty in nooks and crannies. glue the fragments together with 5 min epoxy and place in sandbox to cure. a second pass with the microjack and hand tools to get any stubborn spots and a second pass with the wire brush. infill with epoxy putty and paint the visible water putty not removed to match the new epoxy fills. a third pass with hand tools and wire brush. touch up paint.

Specimen will be stored on display in the cretaceous coast hall
