Stem-Bird Files: Rugops by randomdinos Stem-Bird Files: Rugops by randomdinos
Theropoda>Averostra>Neoceratosauria>Abelisauroidea>Abelisauridae>Rugops>R.primus
Sereno et al, 2004
Time: Cenomanian (97-93 million years ago)
Length: 3.5 meters (11.5ft) based on the only known specimen (a skull).
Height: Slightly above 1 meter (3.3ft) at the hip for the holotype specimen.
Weight: Around 150 kg (0.15 tonnes) for the holotype specimen.
Habitat: Echkar Formation, Niger, Africa.
Ecology and hunting habits: Small terrestrial predator. Like other abelisaurs, Rugops was probably a fast runner (although not as fast as some of it's relatives, like Carnotaurus) that targeted prey smaller than itself.
Diet: Juveniles of other dinosaurs, as well as pterosaurs and carrion, possibly including beached aquatic life, eggs, and other microvertebrate fauna like the tiny uruguaysuchid Araripesuchus.
Competition: The terrestrial(ish) notosuchian Kaprosuchus and juveniles of other theropod species such as Carcharodontosaurus, Spinosaurus and Bahariasaurus. Adult versions of these species were more often than not, likely predators of Rugops, being several orders of magnitude bigger than the small-prey specialist abelisaur.

Update 07/12/17: 
-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.
-Common name (uncreative, but some animals today have their scientific name as their common one too, and Rugops rolls off the tongue nicely).
- d o w n s i z e (based on more Ekrixinatosaurus-like instead of Carnotaurus-like proportions, but even with the latter it should still be 4.4 meters rather than 4.8 as before)
-Minor text corrections.

1.65 m, give or take a couple cm because the outline isn't exact

I am confused, so is Rugops big or small?!!?!?!

In the sense that it weighs more than most humans, Rugops is big.

But it's not 6 meters long, much less 9.

Hello again,
I just took a look at the Wikipedia page for Rugops and I see it also has no accurate life reconstruction (en.wikipedia.org/wiki/Rugops). Would you be alright with this image here being used in a scale diagram for Wikipedia, similar to what I did with your Ekrixinatosaurus? (en.wikipedia.org/wiki/Ekrixina…)

Please let me know what you think. If you do not wish your lineart to be used in any way, I completely understand and will respect your decision. Thanks for your time. :) (Smile)

Hey again!

In the case of this Rugops, it doesn't exactly look like a good base to me, since the resolution is pretty small, but if you think it's enough, I have no problem with it being used (or any of my lineart, for that matter, as long as those based on other people's skeletals also have the skeletal author's permission to go on Wikipedia).

Hello again.
I am easily able to upscale your lineart and sharpen it, so the resolution isn't usually a big issue here. I really appreciate you allowing me to use your work in scale diagrams. They really help pull together the Wikipedia article.

For this Rugops, the skeletal diagram you based it on is actually on Wikipedia already, found here: commons.wikimedia.org/wiki/Fil…
So I think this one is ok, but I will certainly approach other skeletal artists in the future.
Thanks for your time.

It has something really cute going on with that proportionally large head. If you didn't put a name on it I would confuse it for a juvenile.

To think of the awesomebros trying to have Rugops fight carcharodontosaurs and spinosaurs in the past. Not much of a fight now (not sure they would even fight in the first place, but that's awesomebros for you).

sounds like the 4.8 meter estimate or more and it's slightly taller around the woman's chest. Good ol Anthomnia(sarcastic) had a chart about it in his video...

Oh, well. He only used the semi-outdated 4.8 meter estimate; it's a good thing he didn't fall for charts inspired by estimates from the true king of scaling...

Love the skin pattern. :)

So Rugops only cracked nearly 5m? Interesting; most estimates I've seen were more in 6.5m range (though I guess since we only have a skull, it makes sense the estimates vary).

:iconrandomdinos:
randomdinos Featured By Owner Feb 21, 2016  Hobbyist Traditional Artist
Thanks!

Yeah, some estimates put it even smaller (4m). I actually don't know how they got it bigger at all, unless it was based on Majungasaurus or something...

Unless this is a species of Rugops, which wouldn't really surprise me seeing as it's from Kem Kem:

Indeed. I believe that would be similar in size to Ekrixinatosaurus?

Actually, if my current reference for Ekrixi is right, at least 50% bigger.

Yutyrannus Featured By Owner Mar 10, 2016  Hobbyist Traditional Artist
Huh, so that would make Rugops like the second largest abelisaur then, wouldn't it (after Carnotaurus)?
Reply
:iconrandomdinos:
randomdinos Featured By Owner Mar 10, 2016  Hobbyist Traditional Artist
Second or third, I believe (there's an unnamed abelisaur from Kenya that's bigger than Carnotaurus, though initial size estimates of 11m are too high).

I'm doubtful of its attribution to Rugops, though.

to be honest, I don't think many animals can afford to be dedicated scavengers in the first place. even animals like hyaenas are great hunters, contrary to popular belief, they are actually more successful at hunting than lions.

Yeah really, the notion that it was an obligate scavenger never had much evidence behind it. People just went "well the skull was fragile, so it never hunted". I don't think they analyzed the strenght of an axe-jaw method like Carnotaurus would use, or even thought of other possibilities, like say it kicked small prey to death or something.

Rug actually had a pretty long head compared to other abelisaurs:
