Plant fossil?

[Crazyhen]

This is from Xingyi of Guizhou in which Keichousaurus is found.  It looks like a plant fossil and at the back is fossil of crinoids.  Any idea if it is a plant fossil and what plant is that?

Some closer focused pics of the item in question are in order for a proper ID.

Here are a couple of plates I have with a similar look.

Lepidodendon sp. tree scale

Pennsylvanian Period 

Lepidophylloide sp.

Pennsylvanian Period 

 

It would seem the two sides of your plate are from different ages. One from swampy deposits ( tree) and the other from sea deposits ( crinoid ). That is if the item in question is something similar in line with one of these.

Unfortunately it is not with me and so I could not get higher resolution photos.  But it does look like yours.  What fossil is yours?

Could be Lepidodendron, as they lasted up until the Late Triassic, and the sediments are Triassic in age, if they were found with Keichousaurs.   

 

"They thrived during the Carboniferous Period (about 359.2 ± 2.5 Mya (million years ago) and were found until the Late Triassic, about 205 Ma) before going extinct.^[1]"

Global warming was in the end Triassic news. It's easy to see a major hurricane blowing something like it out to sea.

Although crinoids did exist in the jurassic, they are not common.

I wonder if the tracks on the back could be trace fossils.

If they are jurassic crinoids then I would think that to be more significant than the plant.

 

I would also like to see better close up pictures.

Interesting to have both on opposite sides of the same plate. Very cool and collectible.
