This is a very large specimen of Isotelus from the Ordovician of Ontario, Canada. This Isotelus gigas (not the more common I. mafritzi) was recently acquired from a major trilobite collection. This outstretched trilobite is wonderfully articulated and almost perfectly prone. The bug exhibits very fine detail - the small, crescent-shaped eyes are easily seen. The thick-shelled exoskeleton is beautifully preserved and contrasts strikingly with the lighter-colored matrix. The trilobite is well centered on the rectangular block of limestone. And it is one of the more inflated and 3-D examples of this type we have seen. This is a large, excellent example of an Isotelus gigas from Ontario - a true collection piece.
