Sydneylh Posted October 28, 2015 Share Posted October 28, 2015 I'm not sure what these are of, but I found this piece of limestone in Iowa. I am curious as to what they long skinny fossils are of. Thank you for any help! Link to comment Share on other sites More sharing options...

Fossildude19 Posted October 28, 2015 Share Posted October 28, 2015 I would lean towards a trace fossil - something like THIS, perhaps?

Herb Posted October 28, 2015 Share Posted October 28, 2015 could be urchin spines or trace fossils. not enough detail to say "Absence of evidence is not evidence of absence"_ Carl Sagen No trees were killed in this posting......however, many innocent electrons were diverted from where they originally intended to go.

Al Dente Posted October 28, 2015 Share Posted October 28, 2015 The rock you have is called "Anamosa Stone" and is actually dolomite that is quarried as a building stone from quarries around the town of Anamosa. It is Silurian in age and is part of the Gower Formation. The rod shaped fossils you found are common on the bedding planes but their identity is unknown.
