Paleonet: Permian fossil identification

The fossils have irregularities in diameter and some show semi-regular growth constrictions. This is incompatible with scaphopods. Although some late Carboniferous and Permian do reach a size comparable to these fossils, there would be many long section without growth constrictions, much narrower growth increments for Plagioglypta, and some indication of ribbing on Prodentalium. The thick shell wall and size suggest that these are tubes of a syringogporid coral. This looks like a pile of coral pieces concentrated by currents after being broken from a colony or group of colonies.

Dear Paleonet users,

We recently found abundant small tube-shaped fossil shells from Permian rocks in eastern Australia (as shown in the image below). I was told that they might be the shells of a type of foraminifera. However, some of my colleagues do not agree.

Could you give me any of your opinions about the fossils?
