These ones (above) were found in a lake bed in Botswana from between 10,000 to 250,000 years ago!
The implementiferous bed runs in beneath the Forest Bed strata and the glacial deposits which form the cliff, some 200 ft. in height. The material of the axe is of flint, the colour of the flaked surfaces being jet black.
The ridges and outstanding parts are abraded, and it is striated in places. There is a small area of the cortex remaining, which shows a ferruginous staining. It is a specimen of the ‘platessiform’ type, that is, rhom-boidal in section in the anterior portion and showing the remains of both the dorsal and ventral planes or platforms of the rostro-carinate stage.
In two other specimens cited for purposes of comparison, coming from East and West Runton, one is clearly of the “‘platessiform’ type, but the ventral plane is partly transformed into a cutting edge, while the second is equally clearly of the ‘batiform’ type, in which the section through the anterior portion is triangular in section, the lower angles of the triangle representing the cutting edges. Hand-axes showing these characteristics have been discovered not only in England but also widely distributed over the earth’s surface.
The numerous specimens discovered in the basement bed, belonging to the early Pleistocene epoch, are as highly specialised as are those of any later prehistoric period and represent a very definite and necessary stage in implemental development. No adequate explanation of the purpose which the gigantic size of the Sheringham axe could serve has been offered.
A pyramidal structure found in the Ecuadorian jungle revealed some interesting finds such as this (below)
Amongst these tools are some that would be extremely difficult for a normal size human being to use in any practical fashion, this has led to a strong suspicion that this is one of the legendary lost cities of the giants, well known in local Ecuadorian legends about the Amazonian area, such places generate great fear among the members of today’s jungle tribes as they are believed to be protected either by spirit guardians or by beings not of this world.
Many explorers have gone into the jungles around this area and failed to return – it is certainly known to be dangerous to enter for the foolhardy traveller. Even the most expert explorers have vanished without trace in the hunt for lost cities and the supposed existence of immense treasures to be found.
It would appear that ancient man was either very ambitious in the design of some of his implements which would not be ergonomically feasible, or these gigantic implements were not made by Homo sapiens. Considering the amount of work that went into making these implements, frivolous reasons seem to be low on the list.
So, who made them and what were they like? What did we as Homo sapiens learn about making swords, axes and hammers, mining and building with stone from this previous form of man? Perhaps we should start looking at some "inferior" forms of megalithic structures and tools and see if perhaps that was Homo sapiens formative years of imitating the creators/masters? Eventually, we should be able to know who to credit for amazing finds - the local Native people or the originators.
