DailyDirt: Looking Back At Ancient Humans

from the urls-we-dig-up dept

Our ancient ancestors had a pretty tough life without fire, farming techniques and 4G wireless internet connections. But they managed to create cave paintings that still exist today, and we're still finding cool stuff that pre-historic people left behind. Here are just a few interesting links to our great-great-great...-great grandparents. If you'd like to read more awesome and interesting stuff, check out this unrelated (but not entirely random!) Techdirt post.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

–The Techdirt Team

    The rest of the dinosaurs died out as the result of a nuclear winter brought about by a metor impact. Meanwhile, the then evolving mammals were safe underground. The impact crater just happens to be in the Gulf of Mexico near the Ucatan Peninsula.

    People often ask how we know this and I only respond like this:

    There is a layer of earth where we see a grey vein. The vein appears just below or above everywhere we have found dinosaur fossils. Above this line we find very few species, below we find a ton of them. The grey line is a vein of decaying uranium (which is safe to touch considering the age) so based on the measurements of the half-life of uranium we can deduce roughly when an impact happened. Judging by the measurements, 65 million years is fairly accurate.
