Description
Allosaurus fragilis
Named by Othniel Charles Marsh, 1877
Diet: Carnivore (Prey included Stegosaurus, smaller theropods such as Ornitholestes, ornithopods such as Camptosaurus, and mostly the young of the sauropods such as Diplodocus, Apatosaurus, and Camarasaurus; it may have also been an opportunistic scavenger)
Type: Carnosauria (Allosaurid) theropod dinosaur
Size: 28 feet (8.5 meters) long and around 1.8 tons [Note: Some of the fragmentary remains show that some can grow to 39 feet (12 meters) long]
Region: North America (Utah, Colorado, and Wyoming USA)
Age: Late Jurassic (155 to 148 million BC; Kimmeridgian to Tithonian)
Rivals: Torvosaurus tanneri, Epanterias (Which may be an Allosaurus species), and Saurophaganax
Episode: Time of the Titans
Info: As deadly and fearsome as Allosaurus was and one of the major predators of its time and place (Morrison Formation), the estimate bite was surprisingly weak, far less powerful than a lion's. But recent studies show that Allosaurus used its head like a hatchet, using its strong neck muscles to ram the teeth of its jaw into the body of its prey and while during impact, its sharp-serrated teeth tear through its victim's flesh and causing it to bleed to death.
Note: Based on while pose based on the skeletal display of an Allosaurus attacking a mother and young Barosaurus in the main entrance hall of New York's American Museum of Natural History.
Well its been a long time coming! After seeing Zootopia in theaters, I've finally made and posted one of the most famous theropod dinosaurs from the Late Jurassic period! The Lion of the Jurassic!
There's more famous Jurassic giants coming up!

Actually fish and Arthropoda do that, but they are smart too.

Some fish (e.g. sharks) do show signs of relatively high intelligence (for non-tetrapods), but arthropods are pretty dumb.
👍: 1 ⏩: 1
Shark intelligence (and the intelligence of most predatory fish) is high in general, not just for non-tetrapods.
also, before you say Arthropoda are dumb, look at jumping spiders. Or the "culture" of giant Amazonian centipedes in Venezuela that specializes in hunting bats in midair, a learned behavior.

"Shark intelligence (and the intelligence of most predatory fish) is high in general, not just for non-tetrapods."
Nah, they don't show anything that gets them to "high for tetrapods" level. And "most predatory fish"? Most predatory fish don't have anything going for them that puts them above other fishes in terms of intelligence. What, somehow, being a predator gives you more intelligence than scavengers and herbivores for no reason? I hope that's not your logic...
"also, before you say Arthropoda are dumb, look at jumping spiders. Or the "culture" of giant Amazonian centipedes in Venezuela that specializes in hunting bats in midair, a learned behavior."
Still not enough to get them to vertebrate levels.

By the same logic, being a tetrapod automatically makes you smarter? (And being predatory or omnivorous does make you smarter, besides elephants and parrots pretty much everything that shows above-average elevens of intelligence is predatory or omnivorous)
Most mammals are at a FAR more basic level of intelligence than you think. The smart mammals are the outliers.
also, jumping spider intelligence is high enough that everyone who studies the subject puts them at vertebrate levels. We are talking about high levels of planning, memory, learning by trial and error, deductive reasoning, etc here.

OK, I might have been a little too nasty, but they would have been as smart as herbivorous mammals and birds (both which are dumb for the most part).
HOWEVER...
Most small fish travel in schools, which could be comparable to herds of land animals.
And whole groups of Albertosaurus? They probably all just ate each other.
Dude, any other amniote could be smarter than dinosaurs. It's not just humans.

You seem to have a tendency to jump to any conclusions that lower the capabilities of prehistoric fauna. I know you don't like overblowing animal's capabilities, but don't you think you're going too far in the opposite direction? That's not any better.
"The smartest dinosaur, Troodon, was only as smart as an emu or opossum, which, to say, is not that smart.
That means that dinosaurs are on the same level of intelligence as amphibians, fish, and arthropods..."
First, how exactly does the first statement lead to the second? Secondly, Troodon's intelligence level is unknown, you're mistaking a comparison of relative brain size for actual intelligence. Such logic would render whales dumber than fish. Thirdly, Troodon's probably not even the smartest dinosaur given how we don't even know it's actual intelligence level. Finally, the smartest known dinosaurs are ravens.
"but they would have been as smart as herbivorous mammals and birds (both which are dumb for the most part)"
What? How are herbivorous mammals and birds dumb? The entire concept of "carnivores = smart, herbivores = dumb" is completely ridiculous. Evolution doesn't hand out advantages based solely on diet.
"And whole groups of Albertosaurus? They probably all just ate each other."
Zero evidence of cannibalism within the Albertosaurus bonebed. The Deinonychus case is irrelevant here.
I would also like to add the Mapusaurus bonebed to the evidence for theropod social groupings. No evidence of cannibalism there.
"any other amniote could be smarter than dinosaurs. It's not just humans."
Old outdated myth. While the actual intelligence level of nonavian dinosaurs are unknown, the extant phylogenetic bracket (modern birds, crocodiles) suggests that archosaurs as a whole is pretty intelligent. I'm pretty sure that dinosaurs would outrank things like lizards and turtles in intelligence (heck, lizards don't even really form social groups at all).

This was an old post; I've dumped that logic by now...

I mean, there was also a time in which I used to tolerate what could be considered as blatant C.megalodon worship. However, now that I think about it, I wouldn't want to border onto mammal-humping mania with that.

Excuse me if I went nasty too.
You do have a point of fish traveling in schools.
There are bonebeds of Tyrannosaurids in America and Mongolia which compose of the following.
* One specific species (ex. Albertosaurus or Daspletosaurus.)
* Different age groups from toddlers to teenagers and adults.
And the fact they were buried at the same place at the same time does suggest a family group or even a small pride (In my personal opinion and the opinion of Phil Curry.)
Note: if mammals and birds are dumb, then what's with the complicated behaviors? (ex. Mating pairs, parental care, social bonds, and teamwork)
👍: 1 ⏩: 1
Well, I honestly think the opposite, seeing as what was the whole cause of the Deinonychus and Allosaurus bone beds.
Also, I just said most herbivorous mammals and birds were dumb. In the case of the mammals mammals and birds, some herbivores, as well as most omnivores and all carnivores, are pretty intelligent.

I've got another one.
You know those tons of Allosaurus specimens with big wounds on them? They do show signs of healing, but in my opinion, that's part one in regards to how they survive big wounds like that. If there were multiple Allosaurus taking care of and protecting a wounded soldier, odds of re-heal are that much greater than they otherwise are by themselves.
Note: How many Deinonychus are in the bonebed that you're thinking about? Because if there's a whole flock of dozens, then multiple groups could have fallen for a baited trap. Same with the 10,000 Allosaurus in Utah.
👍: 1 ⏩: 1
The Deinonychus bone bed was a killsite where the adults got over-excited and started ripping out the throats of the subadults. It doesn't say how many there were, though.
Same thing happened with the Allosaurus.
👍: 1 ⏩: 1
Maybe those Allosaurus were lured into a baited trap?
And if Deinonychus were running around in social groups, inexperienced sub adults might have gotten trampled on by the Tenontosaurus which they hunted.
👍: 1 ⏩: 1
For the latter, it doesn't say how many, but it was at least a group of Deinonychus around 1 Tenontosaurus.
👍: 1 ⏩: 1
I counted about 3-4 sub adults who got trampled by the Tenontosaurus, and as long as there are bite marks on all of those bones, group #1 left the victim half eaten, and a rival group showed up later to eat the sub adult leftovers, when the first party had gone.

Oh wow. My childhood favourite dinosaur, and here it is, in its awesome glory.
Can't wait for Australovenator to show up.

Yeah I know!
Thanks!
I love Allosaurus as well!
👍: 1 ⏩: 1
Indeed.
You're welcome.
That's awesome.

Did you know that Allosaurus is the State Fossil of Utah! Also, since its discovery in 1927, Utah's Cleveland-Lloyd Dinosaur Quarry contains dozens of dinosaur remains, including over 44 Allosaurus individuals but why so many died remains a mystery

Actually, yes. I did know that.

Very nice, you should do a group shot of all the dinosaurs when this is done.

Yeah I should!
Good idea

I'm not sure carnosaurs were ones to have feathers.
👍: 1 ⏩: 1
We don't if they do, good point, but one carnosaur species, Concavenator was found with preserved quills around its arms
👍: 1 ⏩: 1
Well, those weren't true feathers that we know from all coelurosaurs.

Big Al gets its own artwork? Wow! Cool!
Do you plan on doing the Jurassic dung beetles, flea from episode 4, and Cruel Sea horseshoe crabs? I don't know the species for the beetle, but the flea is Sauropthirus and the horseshoe crab is Mesolimulus
I think I've asked this before... ah well.
👍: 1 ⏩: 1
Yeah! Full story life and death
Yes I'm doing the horseshoe crab and parasitic insect, but I'm not sure about dung beetle!
There's a ballad of Big Al children's book and remember baby Al was about to catch a tuatara I think!
Also there was a picture of a small pterosaur feeding on the mouth of Big Al and WWD website says it's a Pterodactylus, but this is inaccurate as it did live in the Morisson Formation (I am doing Pterodactylus from ITW app though)
