Paleonet: Permian fossil identification

My reply to the query about Permian fossils got away from me before I was finished.

They are NOT foraminifera.

Another possibllity is that these could be tube segments of colonial microconchids. Recent work (Wilson et al., 2011, Acta Palaeontologica Polonica 56(4)) documents large colonies of microconchids (Helicoconchus) as being common in Early Permian strata in Texas. They are probably common in Early Permian strata in other regions as well. Also, microconchid colonies were easily fragmented in high energy conditions.

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?
