PostPosted: Apr 03, 2017 11:59    Post subject: What is it?  

I found the pictured sample in a desert wash in the Coachella Valley. I was thinking it might be sand fulgurite, but it is not hollow and there is no glassy aspect to it. I think the area has a geologic story including being a sea floor, so I don’t know – might it be some kind of fossilized sea animal’s construct? Shells are a common find in the area which has been dry land for probably many centuries if not millenia. The material sticking to it is consistent with the loose material of the wash it was found in, but the core as seen on both ends is homogeneous, differently colored and fine grained. Any ideas on what it is I found?

It is about 6" long and 1" in diameter, weighing 7.5 ounces.

Similar burrow are often leaved by sea urchins. They displaced big pebbles and shift the sand from front side to back side during their movement. Short spine sea urchins live inside sand while long spine ones are benthonic.

Dale, Marco and those who took a look,

Thank you for checking my photos and description out and offering your thoughts! I was hoping it was fulgurite, but this is interesting too! Brings Frank Herbert's "Dune" to mind albeit on a small scale. In any case it is pretty it is interesting - unusual to me.
