(CNN)A crew of now-extinct monkeys made a treacherous transatlantic journey on a natural raft from Africa to settle in South America around 35 million years ago, according to a study of fossilized teeth found in Peru.
It's believed the prehistoric Ucayalipithecus monkeys made the more than 900-mile trip across the Atlantic (a narrower ocean at the time) on floating islands of vegetation that broke off from coastlines, possibly during a tropical storm.
"It would have been extremely difficult, though very small animals the size of Ucayalipithecus would be at an advantage over larger mammals in such a situation, because they would have needed less of the food and water that their raft of vegetation could have provided," said lead author Erik Seiffert, a professor of clinical integrative anatomical sciences at Keck School of Medicine, University of Southern California. The study published Thursday in the journal Science.
"This is presumably why most of these overwater dispersal events that we know of in the fossil record involve very small animals," Seiffert said.
Only two other species of "immigrant" mammals are thought to have made what would have been a harsh crossing across the Atlantic, although exactly how they got there has long been a topic of heated discussion.
One was New World Monkeys, or platyrrhine primates, which are five families of flat-nosed primates that are found in south and central America today. The other was a type of rodent known as caviomorphs, ancestors of creatures like the capybara.
The team of researchers found the molars during an excavation of the left bank of the Yuruá River in the Peruvian Amazon. The animal has been named Ucayalipithecus perdita, which comes from Ucayali, the area of the Peruvian Amazon where the teeth were found, pithikos, the Greek word for monkey and perdita, the Latin word for lost.
It would have weighed about 12 ounces (350 grams) and was similar in size to some marmosets that live in South America today....more at source

"Native Americans crossed the Atlantic first" So much for being "native." As for the Vikings, we knew that and it was in the history books in the 1950's. Plus there is some evidence that the Romans and Egyptians were in the Americas as well. I mean, SOMEONE was mining copper ore in Canada a very long time ago. No one seems to know who.

Sure, but back then there was only one confirmed site at L’Anse aux Meadows. Now there’s evidence of other sites.
Other site(s) on Baffin Island, but indications that they went further south than LaM as well. No sites found yet.

No, Aboriginal Americans did not make their way to the America by crossing the Atlantic. The genetics alone demonstrate this. During the LGM, Beringea actually had a rather temperate climate and with an abundance of flora and fauna and at that point, migration patterns of herbivores and carnivores crosses back and forth from N. America to Eastern Asia and back. It was the Paleolithic version of a McDonalds drive through window!
Sure, but back then there was only one confirmed site at L’Anse aux Meadows. Now there’s evidence of other sites. Personally, I think learning more and having more details to work from is an added bonus and at the risk of being a huge dork, pretty exciting
So which is it? Evidence that Romans and Egyptians were in the America’s long before there was a Rome or Egypt? Or nobody knows? See, the oldest known copper mines in N. America are located on Michigan’s upper peninsula and has been dated to 5000 BCE. In other words, it’s 7000 years old. There were no Mediterranean powers at that time who could navigate beyond shorelines. Personally, I think it’s far more likely that the aboriginal population of upper Michigan was mining the copper for tools of which there are many exemplars in the archaeological record.

Thanks for the correction. I though that I had read a couple of years ago that they had also located what the Norse referred to as “Ho’p” in Nova Scotia. I apparently misremembered the article because after going back
And looking, the location they were working with is just the most likely spot for this site based on geographic clues.
I did find it interesting though that new research at L’Anse aux Meadows shows much longer periods of Occupation than was originally thought.
Was there not another site where Norse rope work was located as well? I’m getting a little Ahead of myself though.
Pat Sutherland was investigating sites on Baffin Island until she was shuffled out by Harper. Still don't have the straight skinny on that but things got weird at the Museum of History. I think she continued to publish at a Scottish university. There was an investigation at Point Rosee in south-western Newfoundland based on some satellite imagery, but it did not pan out. We know that they went south of LaM because of the butternuts found there...the sites have not yet been discovered. Hop is apparently an expression of a likelihood, and no actual physical site.

I still find the prospects exciting...and I love our Maritime provinces!

Did you see the recent reports on L’Anse aux Meadows where they decided to dig into a nearby bog and found everything from wood laid down as walkways to remains of flora not indigenous to the Americas. I’ll try to find the article and link it for you.

I'd be interested in seeing that. It's been a while since I was there last. The chatter at Red Bay, Labrador, is that they think the Basque predate Columbus on that site.

It looks like the Bronze age peoples were the ones with extensive sea routes worked out, and then came the Bronze age Collapse. Lots of destruction not much history.

let me know your thoughts on this and I'll actually pull Bones of the bookshelf and read it finally!
