American fishing industry Paleolithic

The finding of a variety of fishing gear and marine hunting, about 13,000 years ago, which have been found in the Northern Channel Islands of California, have revealed the wide variety of marine animals that eat humans from the late Paleolithic and sophisticated fishing industry were able to manufacture.

The study, published this week in the journal Science, scientists University of Oregon and the Smithsonian Institute, describes the setting and lifestyle of the well-known Paleoindian Clovis culture, which extended into North America in search of big animals like mammoths.


now know that not everyone was to explore the great plains, but also stayed on the coast and may even outside the coastal route which took them more easily to the south.

excavations Jon Erlandson and his colleagues on the islands of Santa Rosa and San Miguel, across southern California, have brought to light evidence that their primitive occupants hunted geese, cormorants, finfish, abalone and other small mammals. The sites contain

fluted points (or fishtail), stones in the form of crescent moon and other stone tools that look like artifacts that have been found in other luggers inside the continent, associated with glacial lake ecosystems.

At the time of these early Indian settlements, the two islands were several miles offshore, so it is believed that, in addition, these early settlers must have had certain skills as sailors. But without doubt the most spectacular is the striking of the artifacts that are associated with remains of crustaceans, seals, geese, cormorants and fish, some of which were used as projectiles. "Some are so delicate that only could have been used to hunt on the water" , said Erlandson, who has 30 years researching in the area. "utrafinos Are we speak of a great sophistication in its maritime industries" he concludes.

The excavations took place in three different locations. Most materials, however, are still under the sea, because 13,000 years ago the level was 60 meters lower and these people spent most time on beaches and coastal lowlands that are now submerged.

Erlandson and his team found that the tools were similar to those that also have been found in the Pacific, Japan and South America. Some are semi-circular shaped stones were able to kill birds in flight, as with a shotgun.

six years ago, the researcher has already proposed that Pleistocene sailors traveled from Japan to Kamchatka, along the coast of Beringia and Alaska and then headed south on California.

"The implications of technology and overfishing are magnificent. These deposits indicate that there were very primitive subsistence strategies on these shores and islands with all kinds of animals, including pinnipeds and even a duck extinct" says co-author Torben C. Rick's Institute Smithsonian.

Now, the team presents a new challenge: to find primitive sites further delayed another few millennia coastal migration in the North American continent.
