Around 1999, I decided I needed to do a Grandpa/Grandson project.
My granddaughter had dissected an owl's pellet in school and she brought the bones home. I found enough of a mouse skeleton to make a small diorama of an archaeological dig revealing a "dinosaur" skeleton.
Indiana Jones was big in theaters back then so I decided to call it Indy's Dinosaur Dig.
The scale is HO. The locomotive is HOn30.
