Fossil ID please?

[maunder124]

Is anyone able to potentially ID these large fossils I found at my place of work?

 

I work at a coal mine in central Queensland, Australia and stumbled across this large rock. Sadly I couldn't take it with me because it was about the size of a washing machine lol but I'm still interested to know what these things are!

Ordinarily I might call these layered concretions, but the Ediacaran period is named for a place in Australia, so you better wait for someone more knowledgeable to weigh in.

Do you have any idea what the stratigraphic range is of your mine? Couldn't you ask your resident geologist?

Concretions, for me.

Looks a lot like counter septarian art work too me..
