Description Theropoda>Neotheropoda>Dilophosauridae>Dilophosaurus>D.wetherilii
Welles, 1954
Time: Sinemurian (193 million years ago)
Length: Up to 6.5 meters (21.3ft) when fully grown.
Height:Β Up to 1.5 meters (4.9ft) at the hips when fully grown.
Weight: Up to 350kg (0.35 tonnes).
Habitat: The Kayenta Formation of Arizona, U.S, North America.
Ecology and hunting habits:Β Small to medium-sized terrestrial predator. With teeth that are very long, but thin in cross-section, a notch in the upper jaw and reported swimming tracks in several localities, it's likely that Dilophosaurus was at least partially piscivorous, like the convergently similar spinosaurids. The shape and flexibility of its jaws may not have allowed it to prey on animals as large or larger than itself, and it most likely hunted smaller prey, like the majority of theropods.
Diet: Early sauropodomorphs such as Sarahsaurus, the ornithischians Scutellosaurus and Scelidosaurus, early crocodylomorphs, the cynodont Olygokyphus, and the pterosaur Rhamphinion, as well as bony and lunged fish.
Competition: Juvenile Dilophosaurus would have competed for prey with smaller theropods Coelophysis and Kayentavenator and primitive crocodylomorphs. Adults were most likely the apex predator of the Kayenta, with no competition other than eachother.

The terrifyingly cute, venomous Frilled Lizardilo... wait, wrong universe. What is it with semiaquatic lifestyles these days that everyone's getting into them? Pfft, newbies.
-''Kayenta Lindwyrm''~(c)

Update 06/29/17:
-Lineart completely remade.
-Replaced human scale figure.
-More accurate size estimate, now along the centra as is the norm, instead of in a straight line.
-Removed ''average adult'' estimates, they're dumb.
-Minor text corrections.

Based on skeletal reconstruction by , with minor changes to match UCMP 77270's proportions.

Who would have thought eventually scales would be out of the norm for dinosaurs (at least for therapods)? Also...you...you...you put the dew claws on the outside...sorry, for pointing it out... : (
Just a miniscule detail, doesn't matter much. So might I say, very well done

Probably a less formidable animal for its size than the spinosaurs.

If you read your Duane Nash stuff, the skull morphology is much more robust in spinosaurs than in Dilophosaurus.

randomdinos In reply to acepredator [2016-04-06 23:52:53 +0000 UTC]

For its length, probably, but at weight parity I'd bet on Dilophosaurus being more formidable (it would be larger in visual dimensions than the spinosaur).

Dilophosaurus always intruiged me for some reason; I recall it (along with I believe Ceratosaurus and Carnotaurus) was one of the first dinosaurs I knew of as a kid that broke the whole standard theropod trend I only knew at the time (Tyrannosaurus, Allosaurus, etc.) with it's fancy head ornaments and slender-shaped body. Wonder why JP altered it so much; it was mighty interesting on its own :/

Also, quick question, which silhouettes/references did you use for the outline? It's skull seems a bit different than what I remember...

That's Hartman's newest Dilo, which seems to be based off a subadult (most restorations are either an adult or D.breedorum, or both).

"... it's likely that Dilophosaurus was at least partially piscivorous, like the more basal spinosaurids."

You sure everything's nice and tidy in that sentence?

Yeah, it's a bit too well-known for the estimates to be way off.

(then again, Stegosaurus is well-known, and people keep estimating 9 meters for some reason...)

Walking with Dinosaurs say Steg was 13 meters long.Β  What's the deal there?

SpinoInWonderland In reply to Jdailey1991 [2016-04-06 05:29:05 +0000 UTC]

It never says ~13 meters long, it said that their Stegosaurus was ~7 tonnes. Which is an entirely plausible figure for S. ungulatus or S. armatus.

Jdailey1991 In reply to SpinoInWonderland [2016-04-06 11:08:29 +0000 UTC]

It says 13 meters in the book.

The book deviates a lot from the documentary series itself.

SpinoInWonderland In reply to Jdailey1991 [2016-04-06 15:21:09 +0000 UTC]

Here are some examples:

- The Postosuchus is a male rather than a female
- There are phytosaurs in the book, while they're not featured in the documentary
- Diplodocus takes 12 years to reach sexual maturity, rather than the 10 years in the documentary
- The ceratopsid presented to the female Tyrannosaurus is a Torosaurus in the book, rather than the Triceratops in the documentary
- The Ankylosaurus beats down the Tyrannosaurus to death rather than hitting her once

Oh, and also...

-Plateosaurus utterly destroys Postosuchus
-Cryptoclidus goes all awesomebro (or does he?) and catches a Rhamphorhynchus instead of a fishΒ 
-Instead of harassing a mysterious pterosaur, the Ornithocheirus harasses another Ornithocheirus
-The Ornithocheirus dies a much more painful death
-No Hell Creek dromaeosaur

13m...You gotta be freaking kidding me...

upload.wikimedia.org/wikipedia…

Considering their ''Liopleurodon'' is actually P.macromerus according to , that thing's not any better than the 50-meter Diplodocus or 25-meter Liopleurodon.

Well, 'Siesmosaurus' was pretty flippin' huge, so...

πŸ‘: 0 ⏩: 1

randomdinos In reply to scyther500 [2016-04-06 16:27:14 +0000 UTC]

But still, it was barely half of that size.

(42/25=1.68, 1.68^3=4.74, 4.74 x 11 = 52 tonnes for WWD's Diplodocus)
(32/25= 1.28 ^3 = 2.09 x 11 = 23 tonnes for Seismosaurus)

πŸ‘: 0 ⏩: 1

SpinoInWonderland In reply to randomdinos [2016-04-06 17:45:44 +0000 UTC]

WWD's Diplodocus is actually stated to be ~25 tonnes in mass, and it only mentioned that the old and large individuals could reach over ~40 meters. Given that it was made several years before Scott Hartman's diplodocoid skeletals were a thing, well...

πŸ‘: 0 ⏩: 1

randomdinos In reply to SpinoInWonderland [2016-04-06 18:03:09 +0000 UTC]

So the 40-meter maximum size was just another case of random speculation, like living ''in herds of 30 or more'' and having anurognathid oxpeckers tag along with them, and they weren't stating it to be the average size.Β 

Still inaccurate, but at least not stupidly so for the time.

πŸ‘: 0 ⏩: 1

SpinoInWonderland In reply to randomdinos [2016-04-06 18:05:39 +0000 UTC]

Pretty much, and IIRC, ~40 meters was still a viable high-end estimate for D. "hallorum" back in 1999.

Hah, yeah.

Feathers on a Dilophosaurus... eh, it's not outta the question, but I wouldn't draw them. Feathers are 100% proven for coelurosaurs, but outside that group then it gets sketchy... very sketchy.Β
