Can anyone help ID these fossils given to me with no info on location/period?

[TRexEliot]

I prefer to find my own fossils, but over the years I've been given a handful of things by friends and family. Most of these were given with no accompanying information about the location where they were found or the geological age. I'd be very appreciative of any information people here can give.

The fish could be Dastilbe elongatus from lower cretaceous of Brazil

First one looks to be a Hollardops sp. from Morocco (Devonian). Second one is likely an Elrathia kingii missing its cheeks (Cambrian) Or possibly Asaphiscus (I'm not great on Cambrian trilobites). The last trilobite is a phacopid from Morocco (Devonian), but without a closeup of the eye lenses to do a file count, it may too tough to determine.

Yes, I agree, the second trilobite is Elrathia kingii, I'm fairly certain.

I shouldn't have second-guessed myself! Thanks, Adam!  Asaphiscus has a much more prominent pygidial border.

The fish is likely a Knightia eocaena from the Green River formation, but is very heavily painted over.

Is there any way to remove the paint from these to restore them to their most natural state? A big part of the reason why I don't generally collect fossils that I don't find myself is that I'm not very knowledgeable about discerning what has been restored and what hasn't, and I much prefer things to be in their natural state.

You could try acetone, to see if it will remove the paint. but usually, when this heavily painted, there isn't much real fossil left to be seen, if any.
