Siphonia pyriformis, help reasoning

[Linus]

Hi again.

 

Location Sweden, Kristianstad, upper or lower cretaceous, underwater, sponge.

 

This one I think I've ID'd, but there are a few things that doesn't feel comfortable.

 

I think it is a Siphonia pyriformis. But there are a few problems.

 

1. there are two indentations, both in top and bottom. (and not one in top and an extruded stalk in bottom).

2. The size is quite oversized compared to the Siphonia Pyriformis I've seen on images of. This has bowlingball size.

3. There seems to be a wore down cushion pattern that doesn't fit with Siphonia Pyriformis at smaller sizes.

 

Best regards/ Linus
