Re: Re: [Geology2] Strange sandstone formation



Try contacting Utah's state department of geology and go from there. Usually these folks are very good at offering assistance.

Well, the current stone layer is at about 6000 feet above sea level in a middle layer of the Grabd Staircase Nat Monument of SW Utah. Uplifted since the end of whatever era laid it dwn in the ancient seas that once covered this part of the southwest.

Hi Dave,

I'm certainly no botanist, but cycad bark is more diamond to square shape with a latticework type pattern. This trace fossil contains round indentations. And to our newest member, corals grow best in water less than 20m. It's rare to find them growing well in deeper water. They'll need shallow water because of the symbiotic relationship they have developed with zooanthellae that live within them and provide the photosynthesis the corals need to survive.

However, corals' needs are quite restrictive. The salinity has to be just right, water clarity and temperature, too. If the area where you found the specimen fits the former environment, then you've got your answer.

Good luck playing detective, but most of all, have fun!

Looks like a mold (imprint) of fossil palm or cycad bark.
Do a Google image search for fossil cycad and you'll see several pics that look similar, esp. the one at the bottom of this page:
 
 
 
Hope this helps.
 
Cheers.

Hello, I am a new member here. I love the outdoors and spend much of my off duty hours in it. A few days ago I was hiking on top of the White Cliffs near Orderville Utah 20 miles east of Zion Nat Park, the White Cliffs are part of the Grand Staircase Nat Monument. I found this sandstone slab with the unusual imprint on it shown in the picture I took. The slab was 3 feet wide and tall and the round dips were about 2 inches wide and very uniform as it looks.

Any idea's what formed this? In all my years hiking around this area I have never seen this before.
