Probably Homo Habilis ("handyman"). Ignimbrite, 2 1/8". Mauritania, probably El Mrayer region. Excellent and intact condition, glossy desert patina. There is constant disagreement as to dates of Habilis, and if what we consider Habilis was in fact a single species. Dates to approx. 1.9 million BC.
Solid and heavy Neanderthal cleaver or crusher. Flint, excellent condition. Height 5 3/8". Legal excavation find from Bavaria, Germany. Given the size and very direct, simple hard hammer percussion used to make this tool, I think this could be either an early Neanderthal piece, possibly one made "in the field" for a specific usage, or it might have been made by Heidelberg Man. The ergonomics, while not absolutely definitive, would suggest this was made for a very large hand...
2 beautiful Neanderthal discoid scrapers on flakes. Jasper, heights 2 1/4" and 2 3/4". Fontmaure, France. Legal surface finds. Both on exquisite jasper flakes in excellent condition. Dating to approximately 80,000-50,000 BCE.
Small Neanderthal ovate biface handaxe, flint, height 2 5/8". Intact and flawless condition. Surface find, Grand-Pressigny, France. This is a little gem, extremely finely worked. Difficult to convey in the photos the quality of craftsmanship in this small ovate axe. Approximately 50,000 BCE.
A large mode 1 pebble tool on a flint nodule. Height 3 3/4". Excellent condition, legal shore find from Reculver, Kent, England. Soft sea patina. Very basic chopper/crusher, probably Heidelberg Man. Dates to approximately 500,000 BCE.
