Dicraeosauridae

The dicraéosauridés are sauropodes which are close to the diplodocidés , because their teeth resembles each other much… Many of these sauropodes is small sizes, Amargasaurus made approximately 12 m length!

But, contrary to diplodocidés of the time which populated the North America, dicraeosauridés lived in Africa, Asia and South America. They lived Jurassic means with the Crétacé inferior.

Dicraeosauridés would have followed an evolution quite different from the others sauropodes. This difference would come from their food, instead of nourishing various plants increasingly higher like the Diplodocus one makes, dicraeosauridés would have been nourished species fewer and especially not very high (1 to 2 meters)… from where a regression of the size of the neck.

These sauropodes had also strange characteristics: they had spines along their back, and thanks to these spines they had a kind of peak like Spinosaurus , but for the moment no Paléontologue knows with what that could be useful well. Some advance that was useful to them during the parades and that this kind of peak was coloured sharp colors! If you know what a tooth of diplodocus resembles, you will know what about that of one can resemble dicraeosauridé!

Teeth fossilized

Note: Rebbachisaurus any more is not classified among dicraéosauridés; it now makes party of the new family of the rebbachisauridés , even if these two families resemble each other much… With not confusing!
