1. Misspelling: You might have misspelled the name of a dinosaur. Could it be "Othnielosaurus"? This dinosaur was known for its partial skeleton fossils.
2. Fictional Character: It's possible you're referring to a dinosaur from a fictional work like a book or video game. In that case, the "fossil type" would depend on the fictional world's rules.
Please provide more context or clarify the dinosaur's name so I can help you find the answer you're looking for.
