This article presents an analysis of a newly discovered OH 83 human fossil from Tanzania, dated to about 60-32 thousand years ago. The Ngaloba remains (LH 18) from Laetoli, Tanzania, dated to 205 ± 17,000 or 290 ± 25,000 years ago, include a partial jaw and a well-preserved skull, important for the study of the evolution of the genus Homo in the Middle Pleistocene. LH 18 combines primitive and modern features, making clear taxonomic classification difficult - some researchers see it as a modern human, others as an archaic form. The problem is exacerbated by the fact that the skull has been reconstructed several times and suffered post-mortem deformations, including misattachment of zygomatic bone elements and damage to the left side of the jaw. The researchers used 3D scans and CT scans to analyze the changing shapes of the jaw and their impact on morphological comparisons. The work underscores the need for proper digitizing and preservation of the finds and support for the National Museum of Tanzania to protect valuable fossil specimens.
