Found this in a desert area right in the middle of Phoenix. I took it to some geologists and they said it was coral, and it was impossible that I found it as there is no limestone formation in Maricopa County. Someone suggested that a person threw it there out of a car window. Right. I found it, it's cool and it's mine. For some reason, this board won't let me add photos. This one is 98KB. So here's a link: Coral fossil

Yup, no doubt about it. That's coral. Those geologists think they know it all. I have a trucker buddy who travels all over the country. Whenever he has a day or 2 break between loads, he goes rock hunting. He's constantly finding things in places where they "don't exist".

About has to be coral icatz. Nice find. Welcome to the forum. You have to use a photo hosting site like flickr or Photobucket to post photos.

That interesting about no limestone in the Phoenix area couldn't it have broken away from the Mogollon and migrated here? everyone else does Ha Ha

If you found the specimen in a remote area, and someone said it wasn't supposed to be there, I'd suspect you made a scientific discovery, . . . . but when you find something weird in an urban area its highly likely that its an artifact of man's activity. If you really want to take credit for a discovery and contribution to the geology of Phoenix, you will need to go back out there and find a geological stratum of limestone with coral or one hundred other pieces that look like they were naturally deposited or transported there and not dumped from an end loader. Much is not natural in urban areas, and even rocks can be alien. Just thinking. Tom

Awesome coral! Like Tom said, it's truly amazing whats been hauled all over by man's activities. We have gravel yards here locally with rocks and fossils from all over that end up in folks' yards. I've also found camps or even quite isolated spots on the California desert where there are rocks foreign to the area strewn all over or even in piles. One also has to remember that during pluvial periods, many river drainages were truly monstrous and transported material for hundreds of miles or more. Texas gravel beds are a good example. The gravels of the ancient Rio grande and other south Texas rivers are full of stuff from agate beds all over west Texas and northern Mexico.....Mel

Found this in a desert area right in the middle of Phoenix. I took it to some geologists and they said it was coral, and it was impossible that I found it as there is no limestone formation in Maricopa County. Sure there's limestone in Maricopa County, Arizona--just not a whole lot of it. First, there's a localized exposure of sedimentary Paleozoic/Mesozoic (mapped as undivided) limestone-bearing formations in the Harquahala Mountains northwest of Phoenix. See the geologic map of Maricopa County over at Geologic Map Of Maricopa County, Arizona, prepared by Arizona Bureau of Mines, University Of Arizona. The limestones lie within that blue patch labeled PMu in the Harquahala Mountains. Also, there are exposures of the Devonian Martin Limestone in extreme eastern Maricopa County near the Superstition Mountains.

Yes it was a strange find, but because of its location it's unlikely due to man's intervention. Basically, a desert lot behind the National Guard. I've found a few interesting things there from time to time. Chalcedony, drusy. Not much, not often. There is a little half mountain there, maybe it's washing down from inside that.

No joking. I have a real quartz curiosity to post that I found behind the parking area of our hotel in Flagstaff, and a large amount of obsidian from someone's driveway! Granted, this driveway was right next to a well-known obsidian collecting ground, which was covered in 3' of snow, so I stuck to collecting from some guy's driveway. He didn't mind. The obsidian was everywhere.

Great info. But this was right near Oak and 64th streets in Phoenix.

have you ever hounded in the Salt River? I have quite often. One place I access it is off McKellips Can park right in the dry river bed. I'm not much of a rock hound so I probably over look lots But would imagine it as lots of migrated rocks & things..

But I never see an area to pull off, park and get behind the fence. McKellips and what? I'll have a closer look in the next few days. Thank you!

McKellips just north of the 202 freeway out by the casino Arizona
it drive right through the salt river park on the right side of the road easy access lots of rocks!!!!
I dig there for gold well I just poke holes with my hammer but I figure if there ant truth to Lost Dutchman some of that gold broke loose and is alluvial down from the Superstitions Mountains
don't get me started on the Hohokam Indians but keep your eyes open!
what's your name?

Thanks for the directions! I figure there has to be some good stuff there washed down from the mines up north. Not really looking for gold, but I bet there's some good specimens in there. Maybe silver? Unfortunately, they might be too eroded from water/other rocks/floods to be great specimens. My name is Staci. What's yours?

Hi Staci that's my theory too
so far --just lots of river rock haven't found too much that's really polishable the Phoenix area is really frustrating in that regards but I keep getting this feeling that something good is hidden
anyway my name Ed but most people just call me mostly
mostly

Or whatever they call it these days. I got a map to go there but the weather turned hot.

vaguely it might be in the Dreamy Draw area I recall going into a cave-- back in the day but that might actually have been a mine ?
Cave Creek is another heavily mined area...
