Brevicoceras casteri,  with an example of Hederella filiformis

 

According to their 2008 paper,  "Morphologies and Affinities of Hederelloid "Bryozoans"  ", Paul D. Taylor and Mark A. Wilson "... interpret hederelloids as colonial, phoronid-like invertebrates, with retractable lophophores."

Thanks to Scott (piranha) for the paper listed above. :)

Hey Ron,

 

It is an early cephalopod - kind of like an ammonite. Not straight, but not totally curved either. ;)
