The Trinil site on Java Island in Indonesia is well-known for the discovery of the Homo erectus, previously known as Pithecanthropus erectus, by Dutch anatomist Eugène Dubois. His hominin finds were the first early hominin remains discovered outside of Europe [1][2]. Alongside the early hominin remains, the site has also produced numerous vertebrate fossils [3][4] which have contributed to our understanding of regional Pleistocene vertebrate biostratigraphy [5][6][7][8] and biogeography [9][10]. Additionally, a fossil shell with a geometric pattern, considered the world’s oldest hominin-made engravings was also discovered at the site [11][12].

Laetoli in northern Tanzania is one of the most significant paleontological and paleoanthropological sites in Africa. This series of fossil-bearing outcrops, spanning over 1,600 km² [1][2][3] has produced an extensive sample of mid-Pliocene hominin Australopithecus afarensis, including the type specimen. Apart from Hadar, Laetoli has produced the largest collection of such fossils, underscoring the its importance in the study of human evolution [4][5][6][7].

Notably, the site is best known for the 3.66 million-year-old hominin footprints discovered at Laetoli Site G, approximately 45 km south of Olduvai Gorge. The tracks, discovered by Leakey’s team in 1976 and excavated in 1978 [1][8][9], provide the oldest known evidence of human footprints and bipedalism. The footprints were fossilized when volcanic ash from a subsequent eruption covered the tracks left by three early humans. Since their discovery, the prints have been the subject of extensive research into the locomotion, speed, and behavior of the track-makers [6][10][11][12][13][14][15][16][17][18][19]. The footprints likely belong to Australopithecus afarensis, as fossils of this species, dated to the same period, have been found at the same location [20][21][22].
