I have seen with dinos in grassy plains and I was wondering when did grass become the dominant ground plant I know that I appeared 110mya but when did grass become common

Grass didn't become dominant until after the K-Pg extinction event IIRC. It was certainly around before then, but I don't think it had become especially common or successful yet.

Well, those probably aren't grass in the picture but somekind of grass analog prehistpric plants. I heard there were some kind of ferns and horsetail doing grass's job during that time.

That's what I was going to say as well, the painting isn't really detailed enough for us to know what they are.

It's looking like grass had its origins in Mid-Late Cretaceous India. I think there was some sign it reached the mainland (I think it was Pakistan) by the end of the Cretaceous, where they discovered hallucinogenic fungus spores among it as well.

I'll have to double check this though.

How exactly were they able to tell the spores were hallucinogenic just from fossils? It's not like you can get high off a rock! xD

They were VERY similar to modern ergot, which are known to be hallucinogenic.

Is there a possibility of having bamboo in the Cretaceous?

I can't seem to find much info on the fossil record of bamboo, but I've never heard anything about it being around in the Cretaceous.

Bamboo belongs to Poaceae, and I don't know if they were common and diversified like that in the Cretaceous ...

I don't usually post around here, but I though you guys could help me with this.
I want to subdivide the "Ornithischians" category at the ZT2 Download Library (Here), I already made three subcategories: Ceratopsians, Stegosaurians and Ankylosaurs. Next I was planning in making a hadrosaur category for parasaurolophus, edmontosaurus and such, however I realized some dinos like ouranosaurus and muttaburrasaurus are not in the "Hadrosauridae" family but very close... what would be a good taxon to take as a new subcategory? Not sure if to take Hadrosauridae, Hadrosauroidea, Hadrosauriformes, or "Ankylopollexia" though I don't like that name very much :/

I'd recommend dividing it between Thyreophora, Marginocephalia and Ornithopoda ;)

The problem is those names are not very indicative to a person who is a dino noob (such as me :P )
