Trilobiting Posted April 2, 2018 Share Posted April 2, 2018 I found these near the Valley of Fire in Nevada. From what I've researched, the area used to be underwater from 500 million years ago to 250 million years ago. I presume these are ichnofossils of a burrow made by some animal (brachiopod)? The first photo is a burrow in situ. The second photo shows all three burrows. What do you guys think these are? - Seann "Fossils have richer stories to tell about the lub-dub of dinosaur life than we have been willing to listen to." - Robert T.

ynot Posted April 2, 2018 Share Posted April 2, 2018 They could be burrows or root casts. Both are common in nevada. Darwin said: " Man sprang from monkeys."

Paciphacops Posted April 2, 2018 Share Posted April 2, 2018 The "thing" in the first image looks like a piece of stalactite. Does the cross section of the end show any concentric layers or radiating structures? "Don't force it, just use a bigger hammer" Link to comment Share on other sites More sharing options...
abyssunder Posted April 4, 2018 Share Posted April 4, 2018 Try to make some pictures straight to the ends, to see how they appear in cross section. I'm lealing toward Rhizoliths.
