It looks very similar to a Hadrosaur egg, did you find it yourself?

it looks like some sort of concretion in which the surface was covered with a semi-translucent mineral. it appears as if the mineral below the surface mineral may have undergone expansion due to water absorption or something and cracked the surface of the less-porous exterior mineral. i'm not seeing anything resembling eggshell at all.

I agree with tracer here, seems to be concretion like to me.

Other details like locality, age of the formation, size of the specimen... these would all help with the ID process.

Need more info... geographic location to start and type/age of rocks if you know it.

OK, I found it on 3/4/10 (yesterday). I live in a high desert area of the White Mountains in Arizona. (North East Arizona approx 1/2 way up the State and approx. 20 miles West of NM State line) It is approx. 6"long and approx. 3-3 1/2" wide on one end and approx 4-4 1/2" wide on the broken end. Not sure of the weight as I do not have a scale.

I had put max pic size when I posted this so I am adding more here. Guess I should have cleaned it up a bit prior to taking the pics. The white color is the bottom from how I found it.

I've never seen a dino egg with a smooth surface. The one's I've seen all have a pebbly surface. Otherwise, that really looks like an egg!

Take a magnifying glass over the "shell" and see if you notice anything odd. A dino egg should have some pores in the shell, but I can't tell for your pictures.

Mattison,

Here is an excellent link for your local geology (you lucky person, wish they had something this for TX). Can you zoom in and tell which general formation your find came from?

I agree for the concretion (nodule) of sandstone,there are several pieces of Mica minerals.The cracks are for the thermal excursion that in the desert is very high.However try to show some pics of the surface,thanks.

I agree with the fact that all eggs have pores in it, just because the embryo needs oxygen.
This looks like a concretion of some type...

I had to look at a Chicken egg first but I guess a Gator egg would be a closer match (didn't have onr of those) and looked until my eyes crosses......I am just not sure what i am seeing.

I will try to get closer pictures, crop for a closer look and post them tomorrow (3/7/10)
Thank you

Hey Mattison,,, Im no 'eggspert' but after all the rocks posted on here where the owners of those rocks thought they maybe had a fossil egg but turned out to be a rock, this rock really does look like an egg!

OK, went on a quick hunt in the area that I found this egg/rock. I could not find another rock in this area with this leather look and cracked like this one BUT, I did 2 of similar size. One with a few cracks and pores but is just a rock as far as I can see. The other looks like it has/had some kind of cover 'skin' on it but still looks like a rock to me but what do I know? Here are a few picks. (Opps! this pic is taking up 1.25 MB so will have to post in seperate)

Here are 2 close up shots and then cropped, looks kind of like leather to me but not sure of pores.

Mattison, if you use the link above to determine the geologic formation, then it will be easier for others to give you more information about your rocks. ;)

Best guess as the map doesn't show miles is TRc, Tsy or QTb. I could narrow that down if the map showed the miles but these 3 run along the County road that I live on.

You could go into that map and look for St Johns, as I mentioned, that is approx. 1/2 way up the State and approx. 25 miles west of the NM State line (south of I-40 along the 191). I live east of St Johns approx. 6 1/2 miles.

Hope this helps. Thanks!
