no not the 'floor' but the 'sides'
Certainly Schoch uses the assumption concerning estimated rainfall at Giza over the past 10K years or so to
support his method of dating the sphinx, but the method of dating
itself relies
solely on seismic surveys conducted over the
floor of the sphinx enclosure:
Seismic geophysical surveys indicate that the subsurface weathering of the Sphinx enclosure is not uniform. This strongly suggests that the entire Sphinx ditch was not excavated at one time. Furthermore, by estimating when the less-weathered portion of this area was excavated-and thus first exposed subaerially-one can tentatively estimate when initial excavation of the Sphinx enclosure may have begun. Dr. Thomas L. Dobecki, a seismologist with McBride-Ratcliff and Associates of Houston, Texas, assisted in carrying out some low-level seismic work in the vicinity of the Great Sphinx; this was done with the permission of the Egyptian Antiquities Organization.[17] We were able to gather a quantity of seismic data, and with this we have been able to establish subsurface geometries of the bedrock and have located several previously unknown sub-surface features. Seismic lines taken in front of and along the body of the sculpture on either side-east (seismic line S4), north (seismic line S1) and south (seismic line S2) of the monument-indicate that below the surface the limestone is weathered up to a depth of six to eight feet (1.8 to 2.5 meters). However, along the back-west side (seismic line S3)-of the Sphinx the identical limestone has been weathered only to a depth of approximately four feet (1.2 meters). These results were completely unexpected. The same limestone surrounds the great sculpture (the floor of the Sphinx enclosure where our seismic lines were taken consists of Gauri's [18] Rosetau Member, or Member 1), and if the entire body of the Sphinx was carved out of living rock at one time, it would be expected that the surrounding limestone would show the same depth of subsurface weathering.

he makes a point about all the evidence being circumstantial and suspect. the carving of the head, the monument with the broken wording and so on.
Regarding the proportion of the sphinx's head to that of it's body, there is a well understood reason for this, and it's perfectly acceptable, reasonable and still visible. The crack that runs thropugh the enclosure walls and floor that extends through the body of the sphinx is in a place that
should be occupied by the hindquarters of the sphinx, had it been carved proportionally. It appears that upon arriving at this crack, it became apparent to the carvers that the rear of the sphinx could simply fall away unless they extended the hindquarters well beyond the crack, which it appears is what they did.
So, the proportionality argument is moot.

right now i am leaning to agree with schoch, as his argument makes more sense than the egyptologists. oral traditions are very accurate usually and there would be no reason to make up such a pre-date for the sphynx if it wasn't true.
I understand your inclination on this, though I can't completely agree on the dependability of oral tradition, but to me it's a tricky thing to try to date something based solely on subsurface weathering, for the reasons I previously stated. Certainly the walls of the sphinx enclosure display weathering from what appears to be rainwater runoff to me. But other people that have geology degrees differ in their opinions. Since I
don't have a degree in geology, I don't see how I can simply say that these other geologists are wrong. Nor can I definitively say Schoch is wrong, by the same token. Another unmentioned problem is the uncertainty that comes into play when discussing precisely when there was a wet period at Giza. Seems like every day we are finding out previously unknown facts about the weather, even in the present.
Proponents of the "ancienter" sphinx argument often use the fact that other monuments at Giza do not exhibit this water erosion pattern. That's a reasonable argument to me as well. However, there are many that use the
pyramids to make this point and this is completely bogus, IMO. The pyramids were, after all, completely covered with casing stones at the time, which stones are pretty much now long gone. Other structures in the area that are still there also do not exhibit this sort of weathering, but IMO that is not a
definitive indication that they are much younger than the sphinx. The sphinx is located below the plain upon which these monuments are erected. This means that the sphinx and enclosure walls would suffer
much greater erosion from rainfall than some standing building nearby, due to the pooling of rainfall and the subsequent channeling of rainwater runoff for that entire section of the Giza plateau into the lowest point (the sphinx enclosure itself.)
Schoch
does make a good argument, though.

that he links as proof that there was a previous civilization that existed in the area long before the egyptians (which would upset egyptologists). the infamous pyramid building society of pre-history days.
I do not think there is any reason for Egyptologists to get "upset" if this turned out to be true. Also,
any "previous civilization" would
have to leave traces of their existence behind, I mean more than just the sphinx itself. So while I realize that every cubic centimeter of that section of the Sahara has yet to be sifted through a screen by someone, I also realize that Giza itself is one of the most investigated archaeological sites on the planet. It's not likely at all that any sphinx-carving civilization much older than the early Egyptians took up any long term residence there, because there's just never been anything found that would so indicate. That doesn't mean it didn't happen, it just means that there's no evidence to indicate that it did. Tomorrow, it may be a different story, who knows?
