More specifically, if these were early forest grasses, they may have
lacked the mineral deposits that make modern grasses is so hard on
the dentition of mammalian grazers.
These mineral deposits are just what phytoliths are. On the other hand,
grass-type phytoliths could be older than the grass shape of the whole
plant. Maybe what the titanosaurs ate was an unspectacular forest-floor herb
that happens to be the closest "known" relative of the grass-shaped
I presumed that there is no evidence of anything resembling
hypsodont-type adaptations in dinosaurs?
No... but you wouldn't necessarily expect that in animals that grow teeth
like others grow hair... and the gondwanatheres were hypsodont.
