Dating your skeleton
Because of the rare and fragile nature of many fossils, including hominids, molds are often made of the original fossils.
The molds are then used to create detailed copies, called casts, which can be used for teaching, research, and exhibits.
In contrast, the only damage we see on Lucy's bones is a single carnivore tooth puncture mark on the top of her left pubic bone.
This is what is called a perimortem injury, one occurring at or around the time of death.
After a long, hot morning of mapping and surveying for fossils, they decided to head back to the vehicle.
Johanson suggested taking an alternate route back to the Land Rover, through a nearby gully.
At Hadar, the size difference is very clear, with larger males and smaller females being fairly easy to distinguish. Back to top No cause has been determined for Lucy’s death.
One of the few clues we have is the conspicuous lack of postmortem carnivore and scavenger marks.
All these indicators, when taken together, suggest that she was a young, but fully mature, adult when she died.The shaft is angled relative to the condyles (knee joint surfaces), which allows bipeds to balance on one leg at a time during locomotion.There is a prominent patellar lip to keep the patella (knee cap) from dislocating due to this angle.Back to top IHO has replicas of Lucy‘s bones, which were produced in the Institute‘s casting and molding laboratories.The “real” Lucy is stored in a specially constructed safe in the Paleoanthropology Laboratories of the National Museum of Ethiopia in Addis Ababa, Ethiopia.
