- Allosaurus is one of the most iconic fossils from the Jurassic Period. As a large carnivorous therapod, Allosaurus has been featured in numerous documentaries about dinosaurs, and has come to represent the classic Jurassic predatory dinosaur in our imaginations. With an estimated length of around 6 meters long, Allosaurus was smaller than its much younger cousin Tyrannosaur rex, but considerably larger than Velociraptor. It was one of the climax predators of the Jurassic Period in North America and Europe.
My name is Benjamin Burger and in this video, I’ll telling the story of Allosaurus.

allosaurus is my favorite dinosaur. it all goes back to when i was about 4 years old and saw my older cousin's giant golden book of dinosaurs and other prehistoric reptiles with the rudolph zallinger drawing of an allo attacking a bronto.
I have that book and is also my favorite.
@@Spawn674 thanks for sharing.
This video gave me the truth and meaning of life. All hail lord Allosaurus.
My goodness, professor Burger, I do love these videos so much. Thank you for broadening my knowledge of these amazing creatures which I’ve adored since childhood.
As a kid in the late 80s & early 90s, I was always strangely partial to herbivorous dinos (stegosaurus, diplodocus, ankylosaurus, plateosaurus) but, of the meat eaters, allosaurus was always my favorite (well, in reality, dimetrodon was-at least until I learned in my teen years that it, in fact, wasn’t a dinosaur, lol). The generic large meat eating theropod dino toys that most kids would label as being t-Rex were, to me, always allosaurus. I enjoyed learning the tale of human discoveries pertaining to this Jurassic champion that you cover in this video. Thanks, & keep making more. They’re fantastic.
Thank you! Im fascinated with Dinosaurs and there is not alot if any videos as detailed as yours. Thanks again....ALSO LOVE THE ART
36:16 so Big Al was actually Little Richard :)
I've been putting watching this off for over a year and now it finally the right time. This is calm and informative and I enjoyed it.
I've had the pleasure of seeing the India Wood allosaurus several times at the Denver museum. It's one of my favorite displays in the whole museum. It's also cool to catch one of your videos with the comments enabled. I've watched countless of your vertebrate paleontology videos and have found them to be quite informative. I also checked out your website, and I must say that your artwork is top notch! Thanks for putting out the great content.
I'm comforted by the fact that no one has reported evidence of feathers on Allosaurus. If they looked like big fluffy chickens I would be very upset.
Loved the video! I do wonder though and would love to hear your input on Allosaurus Maximus or Saurophaganax.
In regards to the possibility of feathers atop allosaurus’s head, my thought on the matter is “No. Please, dear God in heaven, please no.” This thought holds true for pretty much any dinosaur that isn’t archaeopteryx, which actually looks good feathered-especially when featured in a Zdenek Burian painting. But not even Burian, the artist who (at least up to this present moment) made the most wonderful, soul stirring, glorious paleoart to ever behold, could make a feather crowned allosaurus look good (and he’s someone whose ridiculously antiquated underwater brachiosaurus painting is so magnificently executed, it can make almost any dino-loving paleontologist yearn for those ideas of yonder days when dinosaurs were seen as cold-blooded, swamp dwelling, slow, dim-witted evolutionary losers!). I know professor Burger likes his headwear, but he can pull it off with super cool style. Allosaurus cannot.
There were those Brighton boys, you know the Punker dinosaurs. Pink hair, studded bodies billyidolasaurus.
Benjamin Burger proves Indiana Jones is no Mary Sue. Chapeau!
3 years late, but the idea of Allosaurus sporting a pompadour makes me love it even more 😅
Allosaurus elvisi😂
🤣Yes!@@MarkFloyd7451
Thank you Benjamin for your most excellent videos. I love your children when they were small which for all I know are at this time. Love of this knowledge shows our innate curiosity for the world we live in as humans. I have honey bees as a hobby and while it makes a mess in our home the amount of knowledge for one type insect and the complexity of raising and being a beekeeper with varoa mites, wax moths, hive Beatles introduced from world trade keeps us busy. I have not even mentioned the bacterial infections. Can you imagine a bee specific cholera type infection that in the overwintering bees gives their gut diarrhea so as to reduce the cluster enough to reduce the 93f° to kill the colony. They don't go in the hive and to fly out in low temperature to excrete this business they do so as not to spoil the nest. Many times in spring when at 40° the snow around the hives has splotches all around but by golly they made it. Love your videos, keep up the good work.
He looks like Little Richard . . . LOL . . . Nice dissertation Benjamin :)
Great video, but I was under the impression Allosaurus specimens are larger than 6m. 9-10m top end?
9-10 meters is a more accurate estimate. Not sure where he got 6 meters from.
I watched this video cuz my anti science parents are taking me to the ark and on the website it mentioned the allosaurus skeleton. Gotta pretend I don't know how evolution works.
How'd it go?
@@ohiologist9256 It's in october.
@@Krebzonide Ah. If you want tell me how it went or vent after you go
How'd it go?
That place is such a scam
Thank you for sticking to the subject and being professional. Tired of cutesy stories from the ones who think the presentation is about them. You are a breath of fresh air.
Great video just one correction his name was James (Jim) Madsen not Madison .
That is correct.
I immidiatly liked the video because you‘re one of the only people to ever mention the swiss paleontology siber team who found big al and big al two who never gets mentioned. It was really unfortunate as the owner of the land that the team bought the digging rights for, had moved the fence of his ranch far out into the public/federal owned country. Big al two was a younger specimen but was more complete then big al. I‘ve seen the specimen several times at the teams own museum here in switzerland!
Big Al Two is the most incredible theropod fossil i have ever laid my eyes upon!
@@theahab it is beautiful indeed!
Very nice video, though Allosaurus was more around 9-12 meters long
That's Saurophaganax length at the upper
Are feathers ancestral in the allosaurid line as they are to tyrannosurids?
I didn’t know the person who discovered allosaurus had my name
I would love to find a dinosaur bone JUST ONCE but Arkansas doesn’t have very many dinosaur fossils.
The specimen that leidy described might have been an allosauriod of some kind
I wonder if allosaurus bite force really was low
Ben you are killing it. I will be checking out your other videos. I always thought that Allosaurus was the Don Mattingly of Dinosaurs, now I know they were.
Hello, thanks for the video, i like it! I have a question: allosaurus fragilis had feathers? or only allosaurus madseni? Thanks!
Hard to say for certain, but at this point, it's generally more likely that a given dinosaur had feathers than did not, doubly so if it was a theropod.
@@aprinnyonbreak1290 I read that carnotaurus had no feathers, and some T-rex didn't have either. But then would it be the same as allosaurus? I'm a teacher and I want to explain to my school students. I love dinosaurs and now they too. I want to explain an example of dinosaurs without and with feathers. Thanks you so much.

Well, to be clear, I'm not a paleontologist, just a hobbyist. I'd follow up anything I say with a round of directed research to fact-check, especially since I don't keep up to date on the stuff I know, and new info may be outdating some of what I think I know. The last thing I want is to spread misinformation.
As far as I'm aware: small therapods absolutely had feathers, we actually recovered a tail encased in amber a few years back (which in itself would probably be really cool material for kids, it should come up if you google "amber dinosaur tail" or something to that effect, near perfect preservation of a dinosaur part, to the point that we know it was chestnut on top, whiteish on the bottom) and it's completely covored with feathers in that sample.
We also know that these feathers ranged from traditional feathers, to much finer, almost fur-like feather filaments, that I believe the current model of pterosaurs are covered in.
There's a particular family of dinosaurs, Dromaeosauridae, I believe, that includes a lot of "velociraptor"-like dinosaurs that are nigh-universally characterized as feathered, so this wasn't a rare thing.
We also know that the scales possessed by dinosaurs and modern birds (around the feet, mostly) are analogous structures, and many bird feet are actually scales, turned into feathers, turned back into scales, so large degrees of variability in scale versus feather presentation would be expected.
I believe (it could be outdated) that the resting theory is that most, if not all larger theropods had feathers when they were young, but may have shed them as they grew up.
Besides that, we've found adult large theropods with feather-like skin impressions, and those without, meaning there was likely a degree of species-specific variation in if they retained them, and where they had them.
There's less evidence, but still some evidence that non-theropod dinosaurs had feathers, as well. I can't recall any specific findings, but I seem to have a memory of a relative of the triceratops having feather indentations recorded, but add an extra shaker of salt to that one.
Feathers as a whole, if I recall correctly, have some evidence of existing on common pre-dinosaur ancestors, supported by pterosaurs having the faux-fur feather filaments though again, I can't recall any specifics to support that besides pterosaurs also having feathers.
Basically, the closer you get to pre-avian dinosaurs, the more likely you are to strike feathers, but evidence exists that the structure could emerge on any dinosaur, and the structure is versatile enough to be of use to dinosaurs not following paths leading to flight.
And there's a really cool preserved dinosaur tail in amber that I think would be loved.
Hopefully that's at least a good start to get firsthand research yourself? I know that knowing where to start can be the hardest part.
@@aprinnyonbreak1290 thanks you so much!!! 👏👏👏
Hello everyone! I sculpt Dinosaurs and other cool and not cool figures. Come in who is interested, I will be glad to see everything. Thanks! sorry for the spam)
How could one be so misinformed in they're presentation but yet talk like an authority on Allosaurus
that drawing looks more like a Dilophosaurus then an Allosaurus
Could the jugal differences along with the size differences just be sexual dimorphism
The bell icon wont let me pick all.
I name the drawing “Dave”
Another specimen is 28 feet long and 6 1/2 tall at the hip

I just finished watching the theatrical silent movie "The Lost World" from 1925. The dinosaur is pictured in that movie with the name "Allosaurus" written on the scetch of it,and is referred to as "Allosaurus" throughout that movie. So the name "Allosaurus" was in use in popular culture at least as far back as 1925. That is a long time before the 1970's. I don't know about the world of science, but I knew that dinosaur by the name "Allosaurus" when I was a child back in the 1960's and I can assure you that name was the name that virtually all dinosaur loving chidlren used for the main predator of the late Jurassic in that decade. I think the dinosaur has been popularly known as Allosaurus much longer than the scientific community may have taken to finally pin that name down.
FYI -- Google will not let me turn on notifications, since they apparently think this is a channel for children.
Allosaurus was much larger than 6 meters for a fact.One Allosaurus is 38 feet long and 16.5 feet tall
