UK Trinucleid Trilo

[Huntonia]

Normally I try to only buy fossils with adequate identification but a while back I impulse bought this small trinuclid from the UK. based on my research it doesn't mach lloydolithus or salterolithus, so I'm inclined to say cryptolithus. What do you guys think?

The arrangement of pits looks similar to Broeggerolithus ... these are difficult to ID when they are not preserved very well.
