An analysis of the provenance of the Matarrubilla stone, a large megalith at Valencina in Spain, indicates that the monument’s builders must have had advanced seafaring technology
I can’t read the full article, but 4,000lbs is nothing to a displacement hull. Your average 40’ sailboat carries more weight than that just for ballast much less cargo! Why is this considered advanced technology?
prehistoric
Though a quick search says we’ve likely had at least makeshift boats for as long as 50 to 60 thousand years so kinda broad span if 3000 bc is the first written history(egyptians, 5k years)
If the monument was built around 5 thousand years ago i guess the timeline suggests there were more advanced boats earlier than we thought, so that’s kinda cool
There’s a link in the post that will help you access the full article.
Concerning your question, I think the answer would be in the following segment:
“The Matarrubilla stone basin is a good piece of indirect evidence, which, in our opinion, proves that these people had advanced raft, canoe or sailing-boat technology.”
For details, here is the paper.
thank you i didn’t see the archive link at all and i was looking! just not awake
