Megalodon is far too small here! And Predator X is too small too.

Ya, this was one of the worst comparisons. Look at the spikes on the Triceratops' back! And the Sperm Whale has no tail! It just has too fins at the back which are pretty much just attached to it's torso. Lol.

About Puertasaurus:

Taxonomy: Sauropoda; Macronaria; Titanosauria; Lognkosauria

Known only from a lower neck vertebra, a front dorsal, and two as-of-yet unpublished tail vertebrae, this creature was colossal, and could easily have been 130 feet (40m) long, perhaps longer depending on the size of its tail. In that respect, this reconstruction is actually pretty conservative.

Dr. Fernando Novas described and named this king of the titans in 2005, and quickly it became clear that even Argentinosaurus was no match for it in the lineup for "biggest dinosaur".

Puertasaurus is a very late-evolving member of Lognkosauria, a strange family of intermediate titanosaurs with extremely massive vertebrae with massive processes, and super-wide hips and rib cages.

I would even go so far as to say this was probably the widest and most voluminous rib cage of any animal known to science - although the ribs are missing, the huge width of the wing-like diapophyses of the dorsal indicates an unusually wide rib cage, perhaps as wide as 7 meters. When alive, the whole animal probably weighed well over 100 tons.

A particularly odd feature of this species is its unusual neck shape - wider than it is deep, and with very squat centra, this design made possible a downright insane range of vertical motion, even perhaps leaning the head back past vertical, but also likely limited horizontal/lateral neck motion to some degree.

Puertasaurus appeared in Argentina some 69 million years ago, long after the first Lognkosaurians, which date back to the mid-Cretaceous - in fact, it's one of the last sauropods to have lived, and certainly the last of the truly gigantic ones.

As with most dinosaurs known from so few remains, any reconstruction is largely speculative. Still, what you see here is the first truly high-fidelity restoration of Puertasaurus and the only one done from multiple views to really give a sense of the animal's 3D form.

Giganotosaurus (though it lived earlier) is included for scale as it was the largest meat-eater.

By the way, Deemwhy, all of your Photobucket pictures aren't showing because they have been deleted or something.

See below for explanation of numbers. Yes they are in a random order but its more...fun.... that way. I tried to point out the main differences, obviously there are lots of little differences. The best thing to do is use a lot of refs. I hope this helps people drawing hyenas. I do plan to do a major hyena tutorial at some point.

1) The hyenas back is more sloped than the wolfs, however the slope is not huge, sometimes it is hardly noticable, the wolfs back is not a ram rod, instead it curves ever so slightly upwards.

2) The wolfs neck appears thicker than the hyenas, though this is due to long fur here, the top and bottom lines move apart from the jaw to the shoulders, whereas in the hyena they run pretty much parrellel.

3) The wolfs chest is flat and the belly slopes upwards towards the back end, the hyenas chest and belly slope downwards and then sharply upwards toward the back end. Wolves are generally quite slender, despite their fluffiness whereas hyenas can be pretty fat.

4) Hyenas have a mane, the hair slopes upwards and can be errected, this is more noticable in other hyena species. "while some have noteable manes while others are merely tufts, the back of their neck does have reversed fur at all times" AddictonHalfWay

5) Hyenas have a far more pronounced carpal joint, in wolves this is barely noticable.

6) The chest and shoulder muscles are much more pronounced in the hyena than the wolf.

7) The wolf's tail is larger and bushier, the hyenas has longer hair which can be bushed out into a 'bottle' brush.

8) The hyenas head is larger in comparison to its body than the wolfs, I did a comparison between hyena and wolf heads here [link]

9) and 10) note the different positions of these parts of the leg with the wolf and the hyena standing.
