So what happened to depicting Titanosaurs with the Alamosaurus' cone shaped osteoderms? 
It was very common now you don't see it anymore

There's one lognkosaur (Mendozasaurus) with osteoderms preserved, and they don't look like those of Alamosaurus, so phylogenetic  bracketing gives the group different osteoderms. The status on basal titanosaurs and other groups isn't very clear.
