What did you learn today? Share it with us!
We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.
Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

Just what we don't need.
ever get the feeling that devil's blood really is the final "fuck you, mammals!" from the dinosaurs?
From the unicellular algae *
It’s much older than dinos.
til 👍
Congrats on joining the daily 10,000.
BTW there were tar pits present in the Triassic. That’s just how old oil is.
Hell, there are still tar pits with mammoths and dino skeletons stuck in them to this day! I saw them when I was 5, and vaguely remember the Le Brea Tar pits. Apparently I charmed the staff with my knowledge of dinosaurs and which eras they lived in. Of course this was the '80s so they didn't have feathers yet.
I thought the animals at La Brea were all from the Cenozoic. There are Dinos in there as well?
I'm probably remembering it wrong. I was 5 and obsessed with dinos.
I wish there was a huge tar pot full of exceedingly well preserved Dinos somewhere.
so, quite literally there were non trivial stores of energy dense hydrocarbons available almost immediately after the permian? thats pretty wild.
any real evidence for large amounts of abiogenic oil, or is this still on the weird end of strange?
Sorry, meant to say Jurassic. Oil formation time isn’t consensus yet, but it’s estimated it can take as little as a couple hundred thousand years, so it’s possible there were tar pits in the Triassic. I’m not aware of any evidence to it, but I’m no geologist or archaeologist.
As for abiogenic oil, first I’m hearing of it. Not a clue. Seems fringe.
thanks for the update!
yeah, the abiogenesis idea has been around since the 1950s-ish, I think. it comes and goes, but never seems to get fully debunked. current tepid consensus seems to be that its a plausible earth geo-process, but likely only a very, very minor contributor on this world.
really apprreciate the interaction. :-)
