Hominid footprints at Laetoli : facts and interpretations. The history of discovery and interpretation of primate footprints at the site of Laetoli in northern Tanzania is reviewed. An analysis of the geological context of these tracks is provided. Comparison of these tracks and the Hadar hominid foot fossils by Tuttle has led him to conclude that Australopithecus afarensis did not make the Tanzanian prints and that a more derived form of hominid is therefore indicated at Laetoli.

An alternative interpretation has been offered by Stern and Susman who posit a conforming “transitional morphology” in both the Tanzanian prints and the Ethiopian bones.

This 70 metre trail was found by Mary Leakey’s expedition at Laetoli, Tanzania in It dates from 3. The trail probably belongs to Australopithecus afarensis and dates from 3.

The footprints show a well developed arch to the foot and no divergence of the big toe. They are of two adults with possibly a third set belonging to a child who walked in the footsteps of one of the adults. The prints to the far right belong to an hipparion, an extinct three-toed horse.

‘Lucy’ Species May Have Been Polygynous

The probable misfit between feet, particularly toes II—V, of 3. Afarensis made the Laetoli trails. We suggest that another species of Australopithecus or an anonymous genus of the Hominidae, with remarkably humanoid feet, walked at Laetoli.

Laetoli, one of the most important paleontological and paleoanthropological localities in Africa, is renowned for the recovery of fossil remains of early hominins belonging to Australopithecus afarensis and for the remarkable trails of hominin footprints. In addition, the faunas from the Upper Laetolil Beds 3. Fossils from these stratigraphic units provide important insights into the faunal and floral diversity during the Pliocene, and they serve as reliably dated reference faunas for comparison with other Plio-Pleistocene sites in Africa.

Therefore, Laetoli provides key evidence for interpreting the diversity of hominin habitat preferences and for understanding ecological changes in East Africa from million years ago. The research effort at Laetoli involves collaboration between more than 50 scientists from a dozen countries who specialize in geology, geochronology, vertebrate paleontology, ichnology, paleobotany, zoology, botany, and ecology.

The main goals of the project are to recover additional fossil hominin specimens and to obtain more detailed contextual information on the paleontology, geology, dating, and paleoecology. Additional finds of Australopithecus afarensis specimens from the Upper Laetolil Beds have contributed new information on the morphology, variation, and evolutionary status of this species.

Laetoli’s lost tracks: 3D generated mean shape and missing footprints

Discovery of Early Hominins. The immediate ancestors of humans were members of the genus Australopithecus. The australopithecines or australopiths were intermediate between apes and people. Both australopithecines and humans are biologically similar enough to be classified as members of the same biological tribe–the Hominini. All people, past and present, along with the australopithecines are hominins.

We share in common not only the fact that we evolved from the same ape ancestors in Africa but that both genera are habitually bipedal , or two-footed, upright walkers.

Laetoli is a site in Tanzania , dated to the Plio — Pleistocene. It is famous for its hominin footprints, preserved in volcanic ash. It was excavated by archaeologists Louis and Mary Leakey in Dated to 3. Now older evidence has been found, such as the Ardipithecus ramidus fossils. The footprints and skeletal structure excavated at Laetoli were clear evidence that bipedalism evolved before enlarged brains in hominids.

Although it is debated, it is believed the three individuals who made these footprints belonged to the species Australopithecus afarensis. Together with footprints were other hominin and animal skeletal remains and Acheulean artifacts hand-axes. After debate, it was decided that Australopithecus afarensis is the species of the three hominins who made the footprints at Laetoli.

Fossil footprints tell story of human origins

The Laetoli footprints were most likely made by Australopithecus afarensis , an early human whose fossils were found in the same sediment layer. The entire footprint trail is almost 27 m 88 ft long and includes impressions of about 70 early human footprints. The early humans that left these prints were bipedal and had big toes in line with the rest of their foot. This means that these early human feet were more human-like than ape-like, as apes have highly divergent big toes that help them climb and grasp materials like a thumb does.

The footprints also show that the gait of these early humans was “heel-strike” the heel of the foot hits first followed by “toe-off” the toes push off at the end of the stride —the way modern humans walk.

Laetoli is the name of an archaeological site in northern Tanzania, where the footprints of three hominins –ancient human ancestors and most likely Australopithecus afarensis –were preserved in the ash fall of a volcanic eruption some 3. They represent the oldest hominin footprints yet discovered on the planet. The Laetoli footprints were discovered in , eroding out of a gully of the Nagarusi river, by team members from Mary Leakey’s expedition to the main Laetoli site.

Three and a half million years ago, the region was a mosaic of different ecotones: montane forests, dry and moist woodlands, wooded and unwooded grasslands, all within about 50 km 31 miles of the footprints. Most Australopithecine sites are located within such regions–places with a wide variety of plants and animals nearby. The ash was wet when the hominins walked through it, and their soft print impressions have given scholars in-depth information about the soft tissue and gait of Australopithecines not available from skeletal material.

Anthropologists have found fossil human footprints, in northern Kenya, dating back 1. This is the oldest evidence so far showing our ancestors walked in a similar way to human beings today. AFP – Anthropologists have uncovered ancient fossil footprints in Kenya dating back 1. The footprints were discovered in two sedimentary layers near Ileret in northern Kenya and revealed an essentially modern human-like foot anatomy.

The impressions came from the Homo ergaster, or early Homo erectus, the first hominid whose longer legs and shorter arms corresponded to the body proportions of the modern Homo sapiens, the study’s authors said. The footprints provided information on the soft tissue form and structure that are not usually available in fossilized bones, explained Matthew Bennett of Bournemouth University in Britain, the lead author of the study published in the journal Science. Bennett scanned and digitized the footprint to make sure that comparisons with modern human and other fossil hominid footprints were objective.

The upper sediment layer contained three footprint trails: two trails of two prints each, a trail of seven prints and several isolated prints.

The Laetoli footprints Olduvai gorge, Laetoli. Laetoli is an important paleoanthropological excavation site located in the Ngorongoro Conservation Area, Northwest of Lake Eyasi, 45 km South of Olduvai, another rich archaeological site in Tanzania. Not far from Laetoli is the extinct volcano Sadiman, which was very active about 4 million years ago and during its eruptions emitted a cloud of ash made up of carbonatite that deposited on the surrounding land.

Several fossils have been found in the Laetoli archeological site, but the most sensational discovery remains the one made in by the English archaeologist and paleoanthropologist, Mary Leakey, who found still intact the footprints of two hominids. They date back 3. The layers of ash deposits formed by the subsequent eruptions of the volcano virtually “sealed” the footprints and protected them from the effects of weather and other atmospheric agents.

The footprints found, probably belonging to Australopithecus afarensis Lucy , are well formed and unquestionably reveal that the hominids walked standing on two legs and not on four legs. This striking piece of evidence of bipedality, supported by over 50 footprints on a stretch of land of 23 metres, dates back about 3.
