European giants by Durbed European giants by Durbed
Parabrontopodus distercii, the colossal spanish sauropod which presumably could have reached Amphicoelias's size serves as a walking buffet table to a fellow european Torvosaurus, most likely the largest theropod of it's time. This kind of "Rip-and-run" feeding strategies that have been speculated on large carnosaurs could explain why did some sauropods grow so ludicrously huge; their mere size could have helped them to endure this kind of injuries and survive to be bit and partially eaten another day, rather than just persuade the carnivores to stay the hell away from them. Just a theory. Uh, gross.

Epic deviation, but about the description, I'm pretty sure that sauropods had both, the advantage of being able to survive having their flesh ripped apart, and the ability to kick some theropod rear.

Awesome. First of all, glad you're out there still! Second: I think this is the first paleoartistical depiction of the "flesh grazer" speculation I've seen. Congrats!

Thanks man. Yeah, I've been working in several things at the same time, not sure on what should I focus on. Hopefully you will something new quite soon.

Very nice work!

Though I doubt Torvosaurus was that big (in fact the european specimen being estimated at a skull lenght of 1.58m seems to have based on a misquotation, its just a little bigger than the american one). Also, torvosaurus anjd MEgalosauroids may not have employed the same hunting style as allosauroids, having a different tooth and jaw design.

What would it feed upon regularly, otherwise? small-ish camptosaurs seem like they could have been too fast to catch, and contemporary stegosaurs like Dacentrurus were too overly spiky to become the default target. Large and relatively sluggish sauropods or its juveniles look like a safer bet in comparison. Anyway, being an apex predator it could probably handle most kinds of prey relatively well, so maybe even large fishes were also on its regular menu, moreso than other dinos- the elongated jaw makes me think of an early proxy for a spinosaur like lifestyle . But you're right, it wouldn't have hunt like other large theropods it coexisted with, maybe using a more generalistic approach. The teeth, while they appear to be thicker than your typicall allosauroid or ceratosaur are still a far cry from the smashing tyrannosaurian teeth and could retain a lot of the slicing qualities seen in carnosaurs.

Now regarding size estimates, I'm actually not sure.  Even if those are wrong it still makes for some hell of a beast that makes the top 4 or 5 of largest jurassic theropod (what's the source for the misquotation, anyway?). But if we look at things like "Edmarka", the 11-12 meter mark doesn't seem that unlikely really.

I think an animal with a proportionally long skull, banana-shaped, 12.7cm long tooth crown, deeply rooted dentition, deep maxilla indicating a small antorbital fenestra, deep jugal bar, low rostral pneumaticity and a maxillary tooth count of 10 probably has a greatly different biting mode from an Allosaurid theropod with many moderately tall, anteroposteriorly long, narrow and recurved tooth crowns, and a lightly built (though strong), relatively pneumatic and comparatively short skull and an extraordinarily large gape.

Well, Parabrontopodus was also overly large, wasn’t it? Size is at least as good a defense as spikes.

Tyrannosaurs managed to hunt ceratopsians and Ankylosaurs somehow. Torvosaurus lived in a rich ecosystem, feeding on ornithopods (there were actually very large ornithopods in Lourhinha, based on footprints reaching 70cm) and stegosaurs (there were fairly big ones too, as the one you already mentioned).

But my point wasn’t as much about the prey item as about the hunting tactic. Torvosaurus does not seem to be a large-gaped slasher the likes of Allosaurus. That doesn’t mean it could not have attacked young sauropods (in fact those were fair game for any theropod). But I don’t think Torvosaurus was the only apex predator in its ecosystem (again, footprints suggest both considerably larger and several different giant theropods from upper jurassice Iberia), and accordingly not necessarily the one to hunt the really big sauropods. With its massive jaw bones, smaller gape and longer-crowned, more sturdy teeth it would rather specialize in mid-sized (~its own size) animals.

check out the following if you have time:
ICHNOLOGICAL EVIDENCE FOR GIANT ORNITHOPOD DINOSAURS IN THE LATE JURASSIC LOURINHÃ FORMATION, PORTUGAL

and

A diverse Upper Jurassic dinosaur ichnofauna from central-west Portugal
(both Mateus & Milan)


You may be right about Edmarka (at least I think its fairly big, at least 10-11m). The misquotation is simple; the numbers cited by Mateus et al. 2006 were never given in Britt 1991. If you compare the Lourhinha maxilla to the skull of T. tanneri, it is not much bigger.
You can even look at their own skull diagram: public.dm1.livefilestore.com/y…

Huge man!Amphicoelias fragmillus could reach 59 m and even 60.
