1 - DinosaurornithischianThe attachment of the limb suggests a 'bird-hipped' beast.
11 - Saurischiena theropodWas it a carnivore? It has a fierceness to it.
12 - Ornithischianan ornithopodIt looks like it might have been able to rear up on two legs.
111 - Sauropoda titanosaurusThe largest of the dinosaurs, a beast of almost unbelievable height.
112 - Theropoda coelurusA small, agile hunter; the mesozoic's version of a wolf or a fox.

Description summary:
The description varies based on the new level of Proposed Taxon:

Proposed Taxon:Description
12 - OrnithischianIt is, perhaps, a leap to infer the shape of the hips from a limb bone. But palaeontology is a science of careful inferences.
112 - TheropodThis creature must have been a fierce hunter, when it was alive.
122 - OrnithopodYou can see the telltale signs of a versatile grazer, one that could stand on two feet to reach the tender leaves atop the tallest cycads.
1112 - TitanosaurusTitanosaurus is the largest, heaviest beast ever discovered as a fossil – that walked on land, at least. Its legs must have been like the trunks of ancient oak trees.
1122 - CoelurusOne of the smaller dinosaurs, but surely one of the most terrifying ones – like a rabid wolf crossed with an ornery monitor lizard.
1212 - PolacanthusPolacanthus is a strange creature; a bundle of heavy horns and spikes stacked atop a squat quadrupedal body.
1222 - HadrosaurusHadrosaurus had a spectacular crest; alas, your own specimen did not come complete with one.
