He says China is between Turkey and Israel...
Well, he might not be wrong.

I don't think Noah had a GPS or a map when sailing the ark, so he probably lost his way.

We've found several claws, some metacarpals, a few of the dorsal spines, about 3/4 of the radius and a fragment of the ulna, along with many skull fragments. Very recently, we've also found a few pieces of what we think are the ilium and ischium. We've been able to deduce that it had at least 3 fingers on its forelimbs, although there is speculation that there might be a 4th vestigial finger, sort of like a dewclaw.

Even more interesting, is the proposal that Spinosaurus may have been aquatic. That would certainly explain why both the forelimbs and hindlimbs are approximately the same size. It sure looks crocodile-like, so it wouldn't surprise me if it did spend a lot of time in water. I just read an article about that, if you have access to a database where you are it may be of interest to you. It's called "Oxygen isotope evidence for semi-aquatic habits among spinosaurid theropods." :)

I also think that Spinosaurus may have had a fleshy hump instead of a sail because the "spines" look so much like the raised vertebrae in bison, contributing to their prominent shoulder hump.
Actually many experts now consider a ridge akin to that on the backs of some chameleon species more likely than either a full-fledged hump or sail.

Also, double-posting is against the rules.

But yet they would have ran out of food if they traveled to China and back on a boat full of a million+ animals. :P

1.
I think that it's possible Spinosaurus may have been quadrupedal, it's very hard for scientists to make a decision about it though, mainly because our most complete skeleton was destroyed during a bombing in WWII before it was even completely analyzed (our pettiness as a species knows no bounds).

I personally think that Spinosaurus was primarily bipedal, but may have adopted a quadrupedal stance occasionally, just because the arms were so well developed for a theropod during that era.

2.
I also think that Spinosaurus may have had a fleshy hump instead of a sail because the "spines" look so much like the raised vertebrae in bison, contributing to their prominent shoulder hump. In any case, we don't really have enough evidence to be certain, and I think that taking our own creative license on Spinosaurus would be best.

At least one of us has to be correct, yeah? I think quadrupedal Spinosaurus looks really cool, and I have no problem with people who pick either side of the debate.
1.
Incorrect, that skeleton was actually very sparse itself. The Ibrahim neotype is the most complete.

2.
Actually the vertebrae closer to the neck become thinner at the top, very different from those of bison. These structures would not have made an effective surface for attaching a large hump. As Cyborg said something more skin to a chameleon works better here. But the vertebrae over the hips do fan out near the top, similarly to a bison. Spinosaurus probably had what would have looked like two separate structures on it's back, one thinner in front and another thicker behind it. Compare Spinosaurus and Bison skeletals below.

What lolwhat since when did anyone credible think it could have had a fourth finger? That's ridiculous.

2.
That's not a new theory at all, heck even just based on where it was found that was always considered a possibility. It doesn't actually resemble a crocodile other than being an aquatic reptile, genuinely it has more analogues to cetaceans than to crocodiles, many more.

I hate that a scientific name cannot be reused once its determined dubious/a synonym
for example: because Zhuchengosaurus maximus is a synonym of Shantungosaurus giganteus we can't use "Zhuchengosaurus maximus" as a name again
...although correct me if I'm wrong.

TBH I keep using Anatosaurus as a common name. Faster to say than Edmontosaurus annectens.

It can be returned if the dubious genus/species suddenly becomes undubious.

Like Brontosaurus.

Just gonna put it out there, the WWD movie offends me as a dino lover AND as a writer. The fact that they make fun of Chirostenotes for having a weird name SERIOUSLY offends me. Although they get some things right, and they did have Alexornis and Hesperonychus, the rest of this "movie" does not do its namesake justice. The original series rolled in its grave when that sack of *dirty word that is used to describe animal waste* was released

I like it for the animation TBH, but I'll only ever watch it muted. :P

Might I suggest the Cretaceous cut?! No voice overs except narration similar to the original TV series done by Benedict Cumberbatch. It really does let you enjoy the work and beauty of the animation and can be rather enjoyable. Again not as good as the originals but not totally blasphemous.

Honestly I wouldn't be surprissed if that Genus name will one day get ressurected like Brontosaurus, the two species weren't much more alike than a lot of Dinosaurs which are considered different genus.

Whatever you say it's still objectively the most up to date appearance of dinosaurs in mass-media, including documentaries. Something the original couldn't even claim at time of release. I'm insulted that fanboys like you keep jumping down its throat without taking into account the spectacular leaps and bounds it took, especially for a feature film. It isn't the fault of the writers, animators, artists, or even the actors that FOX decided to jump in during the last few months of production and demand voice overs.

It actually has been in the past, I have an authentic and accurate world map of Biblical times to prove it.
