However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.
For example, in 1991, two hikers discovered a mummified man, preserved for centuries in the ice on an alpine mountain.
According to the Journal, Israel and Saudi Arabia have been alligned from the onset of the Syrian conflict, "with Israel supplying Syrian rebels near its border with cash as well as food, fuel and medical supplies for years, a secret engagement in the enemy countrys civil war aimed at carving out a buffer zone populated by friendly forces." The Israeli army is in regular communication with rebel groups and its assistance includes undisclosed payments to commanders that help pay salaries of fighters and buy ammunition and weapons, according to interviews with about half a dozen Syrian fighters.
Israel has established a military unit that oversees the support in Syriaa country that it has been in a state of war with for decadesand set aside a specific budget for the aid, said one person familiar with the Israeli operation.
A special Israeli army unit was created to oversee the costly aid operation, the WSJ reported, which gives Fursan al-Joulan - Knights of the Golan - an estimated ,000 (3,900) a month.
The group of around 400 fighters receives no direct support from Western rebel backers, and is not affiliated with the Free Syrian Army, the official rebel umbrella organisation.
Al-Joulan is the main rebel group coordinating with Israel, according to fighters.
It told the WSJ that Israel's support began as early as 2013 under former Defense Minister Moshe Ya'alon, with the goal of creating a buffer zone free of radical militants such as Isis and Iranian-allied forces along Israels border.
Earlier, when discussing why the Syrian "rebels" fighting Assad are in "turmoil", we said that as a result of the ongoing Qatar crisis the various Saudi and Qatari supply chains supporting the rebels, both in terms of weapons and funding, had dried up due to the diplomatic fallout involving Qatar and Saudi Arabia.
"Together with Turkey and the United States, Qatar and Saudi Arabia have been major sponsors of the insurgency, arming an array of groups that have been fighting to topple Syria's Iran-backed president." We concluded that "the rebellion against Assad now seems moot, which is why the most likely outcome is a continued phase-out of support for forces fighting the Syria government until eventually the situation reverts back to its pre-2011 "status quo." That, however, may have been premature as it was missing a key piece of data, one which was just revealed by the WSJ and which many had suspected.
The seriation of stratified deposits permits archaeologists to assess the relative age of particular styles.
