By , years ago, the pace of innovation in stone technology began to accelerate. Middle Stone Age toolkits included points, which could be hafted on to shafts to make spears; stone awls, which could have been used to perforate hides; and scrapers that were useful in preparing hide, wood, and other materials.
Explore some examples of Later Stone Age tools. During the Later Stone Age, the pace of innovations rose. People experimented with diverse raw materials bone, ivory, and antler, as well as stone , the level of craftsmanship increased, and different groups sought their own distinct cultural identity and adopted their own ways of making things.

His scientific name is Paranthropus boisei, though he was originally called Zinjanthropus boisei -- hence the nickname. First discovered by anthropologist Mary Leakey, the well-preserved cranium has a small brain cavity. He would have eaten seeds, plants and roots which he probably dug with sticks or bones. This model of a sub-human species -- Homo rudolfensis -- was made from bone fragments found in Koobi Fora, Kenya, in The adult male is believed to have lived about 1.
He used stone tools and ate meat and plants. Rudolfensis' distinctive features include a flatter, broader face and broader postcanine teeth, with more complex crowns and roots.
He is also recognized as having a larger cranium than his contemporaries. The almost perfectly preserved skeleton of the "Turkana Boy" is one of the most spectacular discoveries in paleoanthropology.
Judging from his anatomy, scientists believe this Homo ergaster was a tall youth about 13 to 15 years old. According to research, the boy died beside a shallow river delta, where he was covered by alluvial sediments. Comparing the shape of the skull and teeth, H. This adult male, Homo heidelbergensis, was discovered in in Sima de los Huesos, Spain in Judging by the skull and cranium, scientists believe he probably died from a massive infection that caused a facial deformation.
The model, shown here, does not include the deformity. This species is believed to be an ancestor of Neanderthals, as seen in the shape of his face. He lived 56, years ago. His relatively old age, thought to be between 40 to 50 years old, indicates he was well looked after by a clan. The old man's skeleton indicates he suffered from a number of afflictions, including arthritis, and had numerous broken bones.
Scientists at first did not realize the age and afflicted state of this specimen when he was first discovered. Neither of these species was assumed to be particularly intelligent - they had both human and ape-like features, with relatively small brains. However the tools suggest they may have been smarter than assumed. Follow Rebecca on Twitter. Exciting stone tool find in Kenya. Artefacts 'alter migration story'. Earliest stone tools to go on show.

What is certain is that the earliest decipherable inscriptions of history do not pre-date the prehistoric cave art era of the 37th century B. I love the simplicity of the drawings, and yet they also offer a complexity at the same time with their lines and the restricted mediums at hand. It is inspiring to view these and think about our ancestor's way of life, what they enjoyed, and how they expressed themselves.
That is so interesting WH I wonder how old those would be. Must go and read up on that. Thanks for sharing the information. Thanks for an interesting hub.
