Paleonet: Unusual trace fossil

[Paul Blake]

Hi,

I have an unusual trace fossil and I am wondering if people know what may
have made it.  Photo 1 is a picture of the outcrop.  On the left you can see
a sinuous trail and on the right is trail made up of two parallel lines then
a circular impression followed by two parallel lines and a circular
impression etc.  Picture 2 shows a close up of the trail.  The parallel
lines are approximately 7cm long.  The trail continues for about 40m and
crosses itself in at least one place

The trail is from the late Permian part of the Bowen Basin in Queensland,
Australia and the environment is interpreted to be a shallow muddy river.

Any information on what type of creature may have made the trail would be
appreciated.

Regards
Paul Blake
