Youtube video of Thracian treasures of Bulgaria breathtaking!

While I was on YouTube looking for a video about Macedonian tombs I came across this video that gives a wonderful overview of the spectacular Thracian treasures that have been unearthed in Bulgaria. I hope to visit Bulgaria one day and see these wonders for myself!

Seventeen 5th century BCE tombs unearthed in Macedonia

This discovery sounds exciting and very unique. I wish the article had included some pictures. The discovery of the gold chest plate embossed with a sun is particularly interesting. I wonder if the sun resembles the so-called Vergina sun found on a gold casket in the royal tombs discovered by Manolis Andronikos.

This YouTube video includes images of several Macedonian tomb sites and artifacts discovered within them including the gold casket embossed with the Vergina sun. It gets a little political towards the end though. My inclusion of it here is merely for illustrative purposes and does not imply any agreement with any political statements made within it.

Macedonian archaeologists have discovered 17 tombs dating from the 5th century BC in Ohrid, southwestern Macedonia, local media reported Monday. In one tomb, archaeologists found bones of a 15-year-old girl with a unique funeral mask made up of thin gold eye-covers, gold plate for the mouth and a plaque with an engraved sun placed on her chest. "This kind of a mask is unique for the Balkans. Several gold plates were found in Aegean region, but this kind of combination in one grave is unknown," Pasko Kuzman, head of the Macedonian Department for Cultural Heritage, was quoted as saying. Jewelry, golden chains and objects made from amber were also found in the graves. - More: EarthTimes

Neanderthal wound from thrown spear points to Cro- Magnon homicide

For years the debate has raged over whether modern humans may have actually killed off Neanderthals. Finally, it looks like, at least in this one case, scientists may have come up with enough evidence to conclude that the remains of a Neanderthal known to the scholarly community as Shanidar 3, discovered in the Zagros mountains of northeastern Iraq in the late 1950s, was the victim of an attack by a spear-throwing Cro-Magnon rather than a hunting accident or intratribal dispute.

The wound that ultimately killed a Neanderthal man between 50,000 and 75,000 years was most likely caused by a thrown spear, the kind modern humans used but Neanderthals did not, according to Duke University-led research.

Drawing from studies aimed at improving police and prison guard protection, the researchers concluded that the downward sweep of a knife could have the correct trajectory to produce Shanidar 3's rib injury. "Knife attacks generally involve a relatively higher kinetic energy," the report said. However, "whatever created that puncture was carrying fairly low kinetic energy at a low momentum," said Steven Churchill, an associate professor of evolutionary anthropology at Duke. "That's consistent with a spear-thrower delivered spear."

The investigators rigged up a special crossbow to fire stone-age projectiles, using calibration marks on the crossbow to tell them how much force they were delivering with each launch.

Those tests revealed the delivered energy needed to create similar wounds in the ribs of pig carcasses, which the researchers used as an approximation of a Neanderthal's body.

The researchers also used measurements from a 2003 study to estimate the impact of using a thrusted rather than thrown spear, the kind of jabbing that Neanderthals are thought to have employed. That produced higher kinetic energies and caused more massive rib damage than Shanidar 3 sustained.

Another clue was the angle of the wound. Whatever nicked his rib entered the Neanderthal's body at about 45 degrees downward angle. That's consistent with the "ballistic trajectory" of a thrown weapon, assuming that Shanidar 3 -- who was about 5 feet, 6 inches tall -- was standing, Churchill said. - More: ScienceBlog.com
