found on top of his grave. Also, there had been a large fire by the burial site. Shanidar 2 had a "higher cranial vault", and other skull proportions that did not quite match up to the average Neanderthal skull. This may prove that the Neanderthals of Shanidar had more of a "morphology of anatomically modern humans" than other Neanderthals, or that the group was very diverse. This points to similarities between the two species, Neanderthals and Homo sapiens, but it doesn't show any inherit "relationships within that species". Shanidar 3 Shanidar 3 was a 40- to 50-year-old male, found in the same grave as Shanidar 1 and 2. A wound to the left 9th rib suggests that the individual died of complications from a stab wound by a sharp implement. Bone growth around the wound indicates that Shanidar 3 lived for at least several weeks after the injury with the object still embedded. The angle of the wound rules out self-infliction, but is consistent with an accidental or purposeful stabbing by another individual. Recent research has suggested that the injury may have been caused by a long range projectile. This would be the earliest example of inter-personal or inter-specific violence in the human fossil record and the only such example amongst Neanderthals. The presence of early-modern humans, possibly armed with projectile weapons, in western Asia around the same time has been taken to imply that this injury may have resulted from inter-species conflict. However, spears produced by Neanderthals 300,000-400,000 years BP were likely used as projectiles. Shanidar 3 also suffered from a degenerative joint disorder in his foot resulting from a fracture or sprain, which would have resulted in painful, limited movement. The skeleton is on display at the Hall of Human Origins at the National Museum of Natural History in Washington, D.C. Shanidar 4, the "flower burial" The skeleton of Shanidar 4, an adult male aged 30–45 years, was discovered by Solecki in 1960, positioned on his left side in a partial fetal position. For many years, Shanidar 4 was thought to provide strong evidence for a Neanderthal burial ritual. Routine soil samples from around the body, gathered for pollen analysis in an attempt to reconstruct the palaeoclimate and vegetational history of the site, were analysed eight years after its discovery. In two of the soil samples in particular, whole clumps of pollen were discovered by Arlette Leroi-Gourhan in
