Fossil ID Help

[RCJ]

Hi I’m wondering if anyone can help me ID these 2 fossils I picked up.  I was told they were starfish tentacles or some type of tentacle. They are not goat horns or animal horns as I am familiar with that.  I cannot find any info??

Looks rugose corals to me.  Definitely not horns or tentacles.

Location and geology could help narrow it down some.

Looks like a dead ringer for: Heliophyllum annulatum

 

"Corallum simple, elongate, gradually expanding, usually compressed; exterior with prominent rounded or sub-angular annulations of growth, which are sometimes at regular distances apart, also concentric wrinkles and fine striations; longitudinal striae distinct; number of lamellae from sixty to seventy-five; height of corallum from one hundred to one hundred and fifty millimeters, or more..."

and some very large and very nice ones at that!

Those are beauties!  Looks like a great ID on them, now I'm just curious where in the world these samples are from?  I see them reported from Pennsylvania.
