French Young Adults Excavate 560,000-Year-Old Tooth in Arago Cave - http://clapway.com/2015/07/29/french-young-adults-excavate-560000-year-old-tooth-in-arago-cave-346/

History of the Arago Cave


The area of the Arago Cave is probably most well-known for the finding of the Tautavel Man fossil. The fossil was one of the oldest fossils found to date. Until this past week.


The cave was thought to be occupied around 700,000 to 35,000 years ago, as the findings have resulted in a variety animal, human bones, and tools. All a different age that suggests the cave was occupied at various points in the past.


It would make sense, as the cave is overlooking a valley which can make for a bird’s eye view below, and make watching the local game a lot easier. Also interesting in the finds is that the species of humans that lived here were capable of speaking as revealed by various skulls. Later experts agreed that the characteristics found were of a pre-Neanderthal Homo erectus, one group before the emergence of Neanderthals as we know it.


The finding of the 560,000-year-old tooth


Which is why the finding of the 560,000-year-old tooth was so significant. The tooth that was found completely isolated from any other fossil with no nearby skull it belonged to was dated to be 100,000 years older than the Tautavel Man.


This was found this past Thursday, when two young French archaeologists began working on the area. There, the 560,000-year-old tooth was found and revealed to be a worn down incisor.


Finding this ancient tooth was truly a great find and very fortuitous as most fossils that date from 500,000 to 800,000 are a rare commodity in Europe, especially since no burials were done then. The 560,000-year-old tooth helps to fill in the blanks for the archaeology community about that point in time. It can also tell a lot about the lifestyle existing during that time. The person that was supervising the excavation site was Amélie Vialet, a paleoanthropologist.


The site of the Arago Cave has been a point of interest for scientists and have turned up many interesting finds about that lost prehistoric era. At the moment–although it is highly doubtful–the team is hoping to find the body the 560,000-year-old tooth belonged to in order to get more information on the people who lived before the Neanderthals.

Fossil Mystery: The Snake That Could Walk - http://clapway.com/2015/07/24/fossil-mystery-the-snake-that-could-walk468/

Snakes Today as We Know them


Today, we are surrounded by thousands of different species, and several new ones that are discovered every other day but take a while to get classified and released officially. At the moment, there are more than 3,000 species of snake, some venomous and some not.

However, what you don’t expect to make the list, even among snakes that can swim, fly, etc., is the snake that could walk.

Oh yes, on the 16th of June this year, an article was accepted for publication in the Science journal detailing the fossil that was found in Brazil. The fossil was dated to be from the Early Cretaceous Crato Formation of Brazil.


The Find and the science world’s Reactions


You have to wonder when you find something like this if you are not really mistaken—maybe it could be a really long lizard. But, upon further examination, it was discovered that the remains are more serpentine the movement and body type than before. This finding suggests that snakes would have evolved not from marine creatures, but rather from burrowing ones.

A follow-up article was written with this discovery yesterday in Science mag as well. There, the writing goes into a bit more detail about the find, and how well-preserved it was for an early fossil.

However, what’s garnering attention isn’t the scientific research that’s been done thus far. No, instead it’s the past of the fossil that’s pulling in readers.


The Mysterious Circumstances of the Snake that could walk


According to the data provided by the team, the fossil came from northeastern Brazil, However, the question of when the fossil was unearthed is a pressing one, as well as how it ended up in the German museum today. Concerns such as this are important to get some sort of closure on, as in Brazil, it’s been illegal to export fossils since the forties.

However not all are concerned with the illegality of the situation. One of the authors remarked in the article that the discovery was more important, and other concerns not relevant to the study were immaterial.

So, we’ll just have to see what news the snake that could walk brings us, but also whether or not the past of its fossil is resolved.
