Bacculite
by: Doug

I am not sure what you mean by soft body parts but I am 95% certain that your fossil is a bacculite.

Bacculites are related to ammonites but with long straight sections. The fossilized part is the shell. The feathery lines are called septa and mark where the animal has moved up into a larger new section walling off the old section of the shell.

Bacculites were plentiful during the Cretaceous Period.

I am curious about where in Colorado you found this.

Thanks for your submission.
