: Congratulations on your find, you must have sharp eyes.

: One bugging question is the age. Why do the rocks have
: to be Precambrian in age? Traces are extremely rare
: in Precambrian rocks, but are usually assigned to
: Planolites or Neonereites. A paper is now in press
: in the Journal Geol. Soc. London on 600 Ma old
: traces from Scotland, which are claimed to be the
: oldest definite signs of triploblastic coelomate
: metazoans in the fossil record. Your Planolites-type
: traces would make a valuable addition to the pre-
: Ediacara fossil story if the age can be pinned down
: well. Cheers and happy hunting!

:a friend found what may be a tribolite. where can a :non computer wizard go to see representations of these :wonderful creatures?
