Fezouata Trilobites

[JUAN EMMANUEL]

Do you guys think there are two different species of trilobites here? The one on the left has more prominent eyes than the one on the right. I also think that the one on the left is an Asaphellus fezouataensis. 

Right specimen. Note how big the eyes are.

Left specimen with smaller eyes.

They both appear to be Asaphellus fezouataensis.  The one on the left has more prominent eyes because of better preservation.

It also appears that the second specimen still has some matrix in the areas around the eyes which may make them appear smaller than they really are.

There isn't any matrix around the eyes.  It's just a weathered internal cast.

Well hush my mouth and call me mumbles!  I'll take your word for it piranha.  That's why I said that it 'appears' that way!

Appearances can be deceiving.
