Voyages of the Pyramid Builders:
And here is some information from Wikipedia:
Robert M. Schoch is an associate professor of Natural Science at the College of General Studies, a 2 year non-degree granting unit of Boston University. He received his Ph.D. in geology and geophysics from Yale in 1983, and is best known for his argument that the Great Sphinx of Giza is much older than conventionally thought and that possibly some kind of catastrophe has wiped out other evidence of a significantly older civilization. In 1991, Schoch redated the famous monument to 7000–5000 BC, based on his assertion that its erosion was due mainly to the effects of water, rather than wind and sand, and also based on seismic studies around the base of the Sphinx and elsewhere on the plateau.[7000-5000BC being the latest possible date of erosion, the structure must predate that-DD]
Schoch's other theories include the belief that possibly all pyramids — in Egypt, Mesoamerica and elsewhere — represent (in the sense that the general concept of pyramids is inherited, along with many other cultural commonalities) a much older global culture, or at least that there was cultural contact around the world in ancient times. He is also known for his research on the Yonaguni underwater "monuments," where he has dived on several occasions, beginning in 1997; his analysis of the formations is that it is a natural site modified by man to suit their needs. He has said that "We should also consider the possibility that the Yonaguni Monument is fundamentally a natural structure that was utilized, enhanced, and modified by humans in ancient times."
In 1993, Schoch lent his name to a genus of extinct mammals, Schochia, of which Schochia sullivani is the genoholotype.
In 2006, Schoch investigated the so-called Bosnian pyramid excavations, at the invitation of the locals. He concluded "absolutely no evidence of pyramids per se or of a great ancient civilization in the Visoko region." 
Besides his work on ancient monuments and cultures, Schoch is interested in environmental issues (he is co-author of the college textbook Environmental Science: Systems and Solutions) and he is involved in the study of parapsychology.

The point is that there is not just one type of thing that is called a Pyramid. There are basically two things:burial mounds and stepped pyramid temples, or ziggurats. The Egyptian pyramids are basically elaborate burial mounds and their original is the form of low mound called a Mastabah. The Ziggurats are typical of Mesopotamia and have external stairways and temples situated on top. It seems that the pyramids of Atlantis were of both types, and in that case the temple pyramids developed as shrines to the dead, in particular perpetual shrines to the deceased kings at the main city described by Plato. It would seem that this took place in the main temple of Atlantis, the temple to Poseidon and Cleito, and that deceased monarchs were interred there more or less as in the case of important English citizens being interred at Westminster Abbey. The sunken Pyramids of the Atlantic (Connected by a red line on the map below) would have been early Ziggurats that incoporated royal burials and perpetual ancestor-worship temples for them. These pyramids would have been spread on either side of the Atlantic in the same way as hypothesized by Thor Heyerdahl in his Ra and Ra 2 voyages, and we can easily imagine that the early Atlanteans went out in reed boats that were copied in both Africa and South America. And that this was at the same time as the Sphynx at Giza was carved. (not the time that the stone facing was put up on it later)
A secondary chain of orange-linked burial mounds is indicated in South Asia for the tradition of Stupas and burial Megaliths in those areas, and these are presumably derived from the West also since they are likewise of later dates. Megaliths in Southern India (and also in Africa and America, it seems) were being used during the days of the Roman Empire.

To quote Dr. William H. Holmes, former Chief Exectutive of the Bureau of American Ethnology, Smithsonian Institution:
Even more diversified and remarkable are the correspondences between the archetectural and sculptural remains in Middle America [Mesoamerica] and those of Southeastern Asia. In both region the chief structures of the cities are pyramids ascended by four steep stairways of stone, bordered by serpent balustrades and surmounted by temples which employ the offset arch and have sanctuaries, symbolic altar sculptures and inscriptions...Temple walls are embellished with a profusion of carved and modeled ornaments and surmounted by roof crests and cupolas of elaborate and even pagoda-like design [with successive tiered roofs]There are present also in Yucatan, as in Cambodia, as supports for the great stone tables, balustrades and lintels, dwarfish Atlantean sculpted figures[in this case "Atlantean" means "Like Atlas", figures standing and bearing up the great weight of other structures above]...The true significance of all this and more has been sought again and again without satisfactory resultBecause of this situation, more than one of the Diffusionists who have remarked on the situation have stated that The Diffusion in this case must go the other way around, with the New World innovators influencing the Old World cultures rather than vice versa.
Maize in Pre-Columbian India
Johannessen has now made three large-scale color photographs available online at http://geography.uoregon.edu/carljohannessen/research.html (new URL, 10/06), with a brief discussion. These photos reveal considerable detail that is lost in the reduced scale black and white reproductions that appeared in the journal article. His photos are the source of the thumbnails on appearing this site, and may be viewed full size by clicking below:
In his 1998 article "Pre-Columbian American Sunflower and Maize Images in Indian Temples: Evidence of Contact between Civilizations in India and America" (see references below), Johannessen goes on to cite several appearances of the sunflower, another New World crop, in pre-Columbian Indian temple sculptures.
