I went with my family when I was 6 years old. They have a little plunger that sits in a container of the tar that you can pull on to get a feel for what the trapped animals had to deal with. As a six-year-old, I did not have strength to pull the plunger up more than maybe 10 cm or so. It was terrifying to think about as a kid. A decade and change later as a grad student, I went back chaperoning undergrads on a field trip and was able to pull the plunger all the way up, but even then, it took effort.
It's an impressive display and really captures both the effectiveness of the traps and the amazing preservation. At most fossil sites you would get excited to find just one intact skull!
The La Brea tar pits are indeed amazing. I was at an AAPG conference in Long Beach and had one day and a long train and bus ride to get there. Well worth the effort! The environmental fallout is also interesting. There were tar seeps all over the area and since bacteria metabolize the tar creating methane every building had a methane monitor. This is within sight of the iconic “Hollywood” sign on the mountain, btw!
I grew up less than 2 miles away from the tar pits and used to ride bicycles with friends; hang out on the grounds, and view the tar pits frequently-2 to 3 times per month. I knew every inch of the buildings and grounds.
Similar issue about 20 Km away in the beach cities of Hermosa Beach and Redondo Beach. There was always globs of tar on the beach and as 6 year olds in the 1970s, we'd track the stuff into the cars on our feet. Sort of ruined the upholstery in the rear seats of my mom's 66 Mustang. The tar issue abated over the years as apparently the source of the seeps was exploited with some inconspicuous slant drilling from shore. About a month ago, I did find a few globs of tar in the sand while surfing a few km further down the coast.

Great video great content.I have one (pardon the pun) bone to pick with you, human migration to the Americas dates have in the past few years been pushed back. Now the prevailing thought is humans skirted the edge of glaciers along ice free coastal corridors prior to the opening of the Bering land bridge. Sites such as Monte Verde in Argentina, The Topper site in South Carolina, even Kanorado site in Kansas hinted at earlier migration, but the real nail in the coffin is the White Plains site in New Mexico. Sediment from footprints found at the site date to 22,800 BP. Lingustic anthropologists and Biological anthros have for decades been suggesting a date closer to 30,000 years ago, archaeology didnt have the data to support it. Just recently are we just now catching up to that. Other than that, the video is great!
Thanks very much. I think the arrival date for humans is the weakest piece of data in this story. I understand it is based on radiocarbon dates of campsites near (but not in) the tar pits. A longer human occupation history would have given more for populations to build up and have an effect, but extinction by hunting still seems far fetched because it was so fast and affected so many different species.
More to the point: there can be no blaming humans for mass extinction of megafauna, excepting perhaps mammoths. Humans were in the Americas for at least ten millennia before the sudden wave of extinctions. We know now that there was a massive comet strike 12,800 years ago that lit off the continent-wide conflagration that did in 30+ genera of megafauna. Martin Sweatman published the definitive review article in, I think, 2019, summarizing investigations at dozens of sites throughout North America and also South America and Africa, and ice core data from Antarctica, with the spike in platinum concentration everywhere. The comet strike _might_ have set off the Younger Dryas cold spell, but definitive evidence to prove that will be long coming. Quibbling over this devastating event has been disgraceful. Boslough and Holliday, particularly, should be ashamed and disgraced. Boslough has promoted the bankrupt argument that because meteor strikes must be vanishingly rare, none could have been so recent, which is both statistical nonsense, and begs the question. It now turns out, furthermore, that strikes are much more frequent than had been assumed. There has been plenty of disingenuous malfeasance to go around.
@@GeologyUpSkill my personal belief (and I'm just an historical archy so take this with a grain of salt) it was a culmination of the two. The climatic changes vastly altered the environment putting heavy stresses on megafauna. I believe humans pushed species teetering of the brink over the edge. If it was just environmental one would expect regional extinction, but an overall migration of species northward to northern latitudes that would have remained or developed similar ecological environs (similar to what is happening today). But if it was solely human driven then we wouldn't see examples like the Mammoths of Wrangle Island which had a population until about 4000BP. Though the island was utilized by the Inuit in this period, did not have the human population like the mainland allowing for a holdout population to survive. Regardless it's a very interesting and dynamic period to study especially when considering our current mass extinction period.
I grew up about 50 miles from La Brea and we made a couple of school field trips to the museum there in my youth. Very interesting place for anyone interested in paleontology.
I'm very happy to have chanced upon your channel. This is my 1st video of yours that I am watching. You're not a natural gesticulator with your hands when talking, I gather, so the fact alone that you have bothered to take the time to be more visually expressive has my respect. I look forward to sharing in your knowledge and passion. Thanks. Subscribed.
I'm glad that you were able to visit! It's a neat place to go and see the bubbling tar pits and all the fossil recovery work they are doing. It's truly fascinating! On the flipside, I've got some Australian areas on my geology bucket list, like Flinders Ranges and Uluru. I hope to go and see them someday.
Fantastic video Nick. So much bad luck for so many animals, however for the researcher/scientist who wants compelling evidence, the tar pits are a fortune almost beyond comparison.

Tar is still bubbling up on the grounds and if you walk around the area you can still find clumps of fresh tar. I have even seen a crayfish in a small creek onsite not far from a tar ball it could have gotten stuck in.
I've of course heard about these all my life. After this video, I'm wondering if the bones that are found are the actual bone material (possibly containing DNA) or has the bone been replaced during fossilization?
At 4:43 you refer to 'current ice age'. Does that mean we are still emerging from the last maximum and are not yet - from a scientific perspective - fully into the inter-glacial period? Not meant as a smarta55 question - just keen to know.
Yes we are technically still in an ice age because there are permanent ice caps on the poles. Take a look at the extended version that is linked in the video description. It has a detailed chart that defines the interglacial period.
@@rodbhar6522 Yes, roughly 10,000 years of remarkably stable conditions. That has allowed us to develop from wandering hunter gatherers into the high tech society we are today. Hopefully we can use that accumulated skills base to adapt to the climate next time it mkaes a major change, regardless of what causes it.
@@GeologyUpSkill Not so permanent as hoped, as it turns out. But we could still tip into another glacial maximum: climate is chaotic, so a quick hot spell could easily kick us off into another mode with unpredictable trajectory.
Just one skeleton of a woman about 10200 years old. Close to the skeleton of a domestic dog that was thought to have been buried with her but later found to be much younger en.m.wikipedia.org/wiki/La_Brea_Woman
The dates I mentioned reflect the oldest evidence of humans near the tar pits. It seems pretty clear that humans arrived elsewhere on the continent much earlier.

Welcome to the climate debate!
I want to visit the tar pits! So interesting.
I can absolutely recommend it!
Tar is still bubbling up on the grounds and if you walk around the area you can still find clumps of fresh tar. I have even seen a crayfish in a small creek onsite not far from a tar ball it could have gotten stuck in.
Surprising only one human skeleton has been found!
I've of course heard about these all my life. After this video, I'm wondering if the bones that are found are the actual bone material (possibly containing DNA) or has the bone been replaced during fossilization?
The bone material is preserved and in some techniques for dating, collagen is extracted to ensure the date represents the bone rather than the oil.
By the way, have fun in the USA. Welcome.
