A new section is being added showing the anomalous egglike formations we have found recently in Grayson County Texas near Lake Texoma.Spheroids embedded in local sandstone occur in the sedimentary detritus used as fill at a semiprivate boat ramp west of Denison.These are in the same area where nodules of almost pure sulphur surrounded by a shell of iron are found embedded in the same sandstones which form the upper layers of the old Red River banks from which Lake Texoma was formed.Beneath these layers are cretaceous marls containing ancient oyster beds and ammonites.Pyrites of iron and sulphur also abound in these layers.Some of these are an unusual silver color as opposed to the more common fools gold and oxidized iron ones.This unusual combination also occurs in a limited zone across the lake in Oklahoma(see the Colbert Creek pages).It was there that we found a large chunk of carbonized wood laced with veins of silvery pyrite in a layer of blue shale near the curious stone wheels.The ball like formations in these recent photos bear many similarities to the stone balls in Costa Rica and Veracruz State in Mexico.There are also many of these stone balls on a hill in Jalisco,Mexico which are composed of fused volcanic glass and explained as natural phenomena of volcanic origin by the National Geographic geologists who examined them in the 60's. These Texomaland spheres do not show any evidence of human artifice that we could discern, yet the natural forces which formed them are quite mysterious in themselves.These anomalies are quite restricted in their distribution so it must be concluded that the forces which yielded them are not uniformitarian ones.
The other egglike objects which exhibit a caviar textured crystal center when opened were found 12 feet down in the ubiquitous blue shale west of Sherman,Texas in Grayson County.The blue shale is composed largely of bentonite which is used in the cement industry. Its blue/gray color is derived from oil deposits which are often found in commercial quantities in salt domes which form reservoirs the extensive chalks,marls and limestones which underlie most of the blackland prairies of North Texas.The chalks of Grayson County are an extension of the Austin Chalk which extends to the Central Texas community from which it derives its name.These huge nodules are composed of an outer layer of limestone encasing a rind of iron oxide,followed by a layer of metamorphic stone very similar in hardness to granite.Inner cores which are often hollow contain water and crystals of calcite together with dark brown to black crystals of unknown material.Similar stones have been found in the Dakotas but these are extremely rare in Texomaland.Geodes of this size are unique in this region as far as I have been able to determine.There are some formations which may be related recently found in Fannin County containing geometric exterior calcite formations.The Soil Conservation representitive found an example in the literature which identify these as concretions.I have found that concretion is a fairly nebulous generic term given to any number of stone objects which exhibit intriguing unusual form.The geologists themselves are somewhat vague in the specifics of their formation and I suspect it is a category of convenience for some.
As a last note,the "Cremo" sphere with the curious hemispheric ring spontaneously split while residing in the plastic organizing tray where I kept it along with other curous relics.Inside was a gray porous ash.These I have learned are also found in Utah and known there as Moquis Marbles.Originally they were declared meteoric in origin but the discoverer has recanted and now claims them to be common sedimentary ------- you guessed it -------concretions.

I met a geologist at the Fannin County Historical Museum in Bonham yesterday.He had just moved to Bonham to an historical old house and had been told to check with Tom Scott the curator on the history of his house.He was looking at the discoids and septarian nodules pictured in the new sections on the main page.He had his own collection of giant septarian nodules from Grayson County and verified that they were from Cretaceous strata.When I showed him the discoid from Wapanucka with the cupule he opined that this was probably a modified discoid.He also verified the black shale from which these came was Jurassic.Since I found the cupule discoid in the Holocene clay in the roots of a tree it seems obvious that this one had been removed from its original setting.He said that Grayson is full of geological anomalies.I look forward to further discussions with him when he gets settled into his new home.

Recently I ran across a photo of some fossil oysters found in Chile.They look very similar to the discoid objects I found in the Jurassic black shale near Wapanucka.That would explain the uniform bands around all of the objects; it would be the hinge of a prehistoric bivalve.It is the closest match I've seen yet.Anyone with other explanations should feel free to put them forward here.

The new addition in Caney Creek 2 is a grapefruit sized sandstone sphere with eyes incised into it with a suggestion of a nose a faint mouth.A much more defined head was recently shown to me and the photographs will be up shortly.The new one is a limestone nodule which has been hollowed out one third of its mass from a quarter sized hole in the bottom.It was eroded from a creek bank in Grayson county and Bulverde points along with some Archaic dart points were found near it. As with most artifacts found in creeks no definite association could be made.

On the Ravenna page are some spheres very similar to the ones in Costa Rica which are linked to an excellent site containing numerous examples photographed by a Kansas University anthropologist.The Ravenna spheres were extracted from a sand mine on the Red River at a depth of approximately 32 feet. Two in particular are almost perfectly spherical while the larger ones are less so.I will be putting up some more photos of sandstone discs which I took on a recent expedition this weekend around Texomaland.Also I have a very curious object which I retrieved from Colbert Creek which is a two and a half foot length of ironstone with the impression of a square beam in it.Likewise there is a photo of a limestone block with a clearly worked edge which was found near the stone wheels.All in all some very curious objects have been popping up all over Texomaland lately.
