I found some unusual structures under the exoskeleton of this Greenops (Middle Devonian) They are auburn brown and somewhat translucent, reminiscent of the material that makes up the exoskeleton of the adult. I only found them concentrated in the area where the exoskeleton of the trilobite came free of the matrix. They are embedded in the matrix there. I did not find any outside of this area in the surrounding matrix. There are a total of 6 of them that are exposed. They are not ostracods. They could be spores, I guess. They could be lots of things, and their concentration within the trilobite could be entirely coincidental. But, Looooooong shot... could they be trilobite larvae? @piranha Below: General location of the objects. Scale in mm. Below: Several of the objects exposed in different positions. Scale in mm (the objects are about 0.25 mm in diameter). This is the best I can do with a dissecting scope. Only other option, if warranted, is SEM (which I can do if necessary).
