The Fauna of the Morrison: Life in the Jurassic 

While Hell Creek is my second favorite fossil formation, the Morrison Formation is my personal favorite because of the multitude of fauna.

I did a presentation on the Morrison Formation for my drama class. I got to educate my class about dinosaurs for 20 minutes, and got full credit! It was one of the best experiences of my oife. Especially because of how receptive and open minded my audience was. I got so many questions that they had to be cut short because of lack of time

I will say this without a doubt, Torvosaurus is HEAVILY underrated. (Don't worry Allo, I still love you)

I had the great opportunity to do my undergrad research on the Morrison Formation and went to Cleveland-Lloyd Dinosaur Quarry in Jurassic National Monument last summer. Helping with excavations and mapping, as well as a few other things, like geochemical analysis. One of the best experiences for sure, and I'm looking forward to returning this summer and to work on my master's thesis on JNM!

I wish Prehistoric Planet would have episodes that focus on dinosaurs from the Jurassic Era, that way we’d get to see dinosaurs like Allosaurus, Ceratosaurus and many other Jurassic fauna be shown with more realistic designs

Very late reply, but thank you for this video! Dinosaur ecosystems are criminally underrepresented in dinosaur media, everybody only focuses on specific animals. Great vid!

Props to you for including Stokesosaurus, I always find that dinosaur really underrated and overlooked. I also renember seeing this species in ZT2 ,love that game, great video!

I love these videos, I love dinosaurs and I’m glad I can learn more about them

I know this comment will probably be overlooked but I just wanted to say that you and you’re videos have gotten me through and out of my depression and anxiety, thank you so much for helping me and I can’t wait for more videos and more faunas. Keep up the outstanding work and be safe❤

The Morrison is just so interesting,my favorite fossil formations have always been Hell’s Creek,Western interior seaway and the Morrison Amazing work as always dude and can’t wait to see your next video!

Wow. The perfect balance of informative entertainment and acknowledgment to the erroneous nature of inferences in paleontology. A healthy dose of cautious skeptisim and utilization of publications that paint an image of these ecosystems as the spectacle they would've been. Excellent video easily one of the best formats I've come across in paleo channels.

Id love to hear more about the dinosaur park formation in upper north america, you did such a good job with the morrison It got me excited that you might do more 👌👌

As I Colorado Native, the Morrison Formation is one of my favorites.

Love it! Morrison Formation is my 2nd favorite of the fossil sites! Please do a video on the fauna and flora of Hell Creek!!

Please make more videos like this, extremely fascinating and informative, thank you.

We are so lucky that bones and other materials, can fossilize! Can you imagine not knowing about any of these great eras of prehistory?!

Now that's what I was looking for ❤

Sad I couldn’t be here when it was live, but at least I get to see it now!

Literally can’t resist watching one of them videos. 😍

The Morrison is my favorite prehistoric ecosystem, not only because of its extremely high biodiversity, but also because of how interesting it is that such a harsh ecosystem is able to sustain multiple a thriving population apex predators and giant and armored herbivores, which are far more spectacular than anything we have today, all at the same place.

I was so lucky to grow up in the Formation area, just west of Denver near the town of Morrison itself. We rode our bikes through Red Rocks every summer weekend, and, oblivious to fossils beneath our feet, lived an exhilarating childhood amongst the meadowlarks, tadpoles and garter snakes of the Cenozoic. To the east a rolling slope decline of the riparian valley fashioned by the Arkansas River hosted pronghorns, Western Quail, Ruffed Grouse, prairie dogs and fenced herds of American Bison. A bit further west into the lingering vestigial wilderness of the Sangre de Cristo Range, the headwaters of the Rio Grande, were cougars, Rainbow Trout, Rocky Mountain Bighorn and rattlesnakes, making life recently ancient to geologists, newly mystical to a kid, and sublime to a desert rat visiting the grand landscapes still surviving from an enchanted memoryscape, 70 years later. West of the Sangre de Cristo huddled the town of San Luis, oldest European settlement in Colorado, and another 100 miles west are the great ruins of the Pueblo peoples' Mesa Verde, in the shadow of the West's most iconic scene imaginable--the Colorado National Monument, where "Butch Cassidy and The Sundance Kid" was filmed, and south of that, the San Juans, 14,000 feet of crepuscular grandeur, the backdrop to the 160-year-old mining towns of Aspen & Telluride. These scenes existed like the Elysian Fields of the New World, until the 1980s, when Reaganomics encouraged suburban sprawl, criminally, to corrupt what was arguably the most sweepingly majestic of all geologic moments of North America. But Southern Colorado, from Morrison to Mesa Verde, is still heaven saddled on the backbone of a continent. Fossils are just its beautiful basement.

My personal favorite fossil formation goes to Hell Creek, but the Morrison Formation takes a solid second place! Great video man, you continue to inspire me to make dinosaur content myself🔥🔥

Great video. Informative and well put together. Only feedback would be to maybe lower the background music a touch so we can hear your amazing commentary better.

One of my favorite formations, definitely. Great info, great pictures, keep it up. Thanks

I love your videos especially these ones. Your the channel that got me back into dinosaurs. Also maybe do a Fauna of Hell Creek that would be awesome. Thank you so much for information.

This is a phenomenal video thank you Dinofax! One of my favorite formations👏

This is better than Netflix😂🎉

So basically, Torvosaurus and Ceratosaurus ambush you in the middle of forested patches, Saurophaganax ambushes you in the periphery of the forested patches. Allosaurus just runs you down on the open floodplains.

This was a very good video the Morrison formation is awesome there were so many Animals living there!

You need to do more formations this was great!!! I’d love to see you cover hell’s creek.

Thank you for this deep dive in to the morrison!

So much depth so much content bravo sir you have impressed me.

You could do Portugal Lourinhã formations. The Portuguese Torvosaurus was bigger than the american. We also had similar animals.

This is so interesting and amazing, thanks for your effort and hard work and passion.

Idk how I’m just seeing this, but awesome vid! Also, great taste in a nanosaurus drawing at 10:16😉

Great Video! I learned so much from you!

It is probably the most iconic formation of Jurrassic period.

brilliant video - packed full of information

I'm so happy you're blowing up good job dude here from tiktok🎉

Thank you dude, having someone actually look a the Morison formation

Thank you for addressing that there was another type of plant filling the niche that grass would one day fill!! I feel like this is a confused subject for most. I’ve long assumed ferns would have filled a niche similar to our grass today, and your video helps confirm that. Some paleo-artists and experts just draw or think dirt because their minds are going, “Welp! There was no grass yet!(?)🤷🏻‍♂️🤷🏻‍♂️”, and I tend to disagree with their line of thinking.

YES MY BOIS SAURO AND TORVO MADE IT

This video was amazing, can't wait for the next one And I wish you have a great day

Love the video man. The info is very helpful for a personal film project I'm working on.

The background music is kinda soothing. Just needs to be a bit quieter. More long form videos like these please 🎉

DinoFax i Love All Your Posts And i Love Dinos 🦕🦖 i Always Look Forward To Your Posts Love Ya❤

The complex overlap of many species gives me awe.

Yes!!! This is at 11 p.m for me so I can actually tune in on the premiere! Leesssgooo!!!

Might be a little late on this but I was hoping that you could possibly do a video similar to this on the Portugal formation and the differences between that and the Morrison

Loving the videos made for youtube instead of compilations from TT.

Fantastic video. Very enjoyable. I would love to see any dinosaur related fromation like the kem-kem or Patagonia

morrison formation is my favorite, especially talking about sauropods n theropods

I love your videos

Can you do the Hell Creek Formation Next Please.

Thank you for taking time to talk about plants

really good thank you!

This video is going to be so awesome

Really nice video, would like to see more of these fauna video, as it can make it a bit more clear of where dinosaurs would have potentially met, rather then thinking that a Dino from Antartica maybe met one from Europe.

This was excellent 👏🏻

Wonderful job

great video, it's really a pity that they seldom show the whole concert of the living species in a prehistoric ecosystem. thanks for catching up here. for next, how about Tendaguru Formation, Trossingen Formation or Messel pit?

Watching as it releases 🎉❤

This is amazing! You should do the Dinosaur Park Formation.

Amazing Video :)

Great Video

I would like to see hell creek. Also cool video

If you ever have time you could do a video like this about Nemegt frormation from Asia

Finally more dinosaur content

W vid definitely should do the Sigma Hell Creek formation

great video

Love longer videos!

I wanna dedicate my life to become a Paleontologist and study both Morisson and Cedar Mountain. They are my favs

It’s crazy he finally made it

This is indefinitely the type of place id visit if I could takr a time machine anywhere with a like indestructible bubble around me lmao. Imagine actually seeing it while everything was alive itd be honestly otherworldly

Good Job.

Population density per species would be an interesting thing to explore, even if it were highly speculative.

Found 2 partial jaw bones, with teeth, in the oil springs area in wyoming belonging to smaller crocodiles. They were about as long as a finger. Lots of turtle shells and traces of the tree stumps left in what was ounce a swamp before it became a geyser feild. Where opals are now found.

Looks like I’m spending 2 months in the Morrison this summer

I would love the Burgess Shale to be presented, I am just a huge stickler for Cambrian animals, maybe also the Chengjiang Fossil site as well 😁

Please do one of the Hell Creek Formation if you haven't already. I'd like to see that.

this is gonna be epic

Hell Creek for sure is another one to make a video about.

Undoubtedly the Serengeti of the Mesozoic Era! Also: I recommend the Yixian and the Nemegt Formations as possible candidates for future videos.

You should do a Bonus talking about MOR 693 aka Big Al/Big Alice

21:14 this is the case for prior extinction’s torvo Also what happened to Epanteria and Mesadactylus?

Yes plz do more formations

Just got on to watch it

I would love if you brought attention to other formations like Kem Kem, dinosaur park or the Yixian formation in the future amazing video as always

You forgot that Dryosaurus was likely the size of a horse since the specimens we found weren't fully grown

Do the hell creek formation please

I have a question, since Ceratosaurus, Torvosaurus and some others are more rare in the area could it be possible they’re actually more common in some other area and the Morrison is more of Allosaurus turf? I might be coping cause I’m of fan of Cerato and Torvo but it is interesting to think that there might be a place these other two ruled.

Woo les go new video

If there’s a season 3 of prehistoric planet they NEED to cover the Jurassic

I think that what people forget about is that Dino’s are close to birds(therapods specifically) and share some traits such as the intelligence of therapods being a lot higher than we thought. That being said, birds flock together to do certain things, and I think it’s likely that allosaurus created a type of temporary flock to hunt. Not necessarily like Komodo dragons where they jump it and then kill eachother. Also, what’s the deal with Epanterias?

Hell creek would be a good one for you to do I liked this one a lot

I can't wait

I can’t wait

Like the music btw and do hell creek formation

We need more videos from fauna from prehistoric times from realife.

I really enjoyed watching this video, but I hope that you’ll be using different background music in the future as it’s too repetitive. And by the way, I appreciate the topic of this video - I haven’t heard such a complete breakdown of the Morrison formation before, and I follow a lot of prehistory focused channels.
