This is a nicely articulated specimen of Dalmanites limulurus from the Silurian of New York. The trilobite is well articulated and wonderfully prone. The compound eyes stick up above the flat, sleek carapace of the trilobite and display the individual lenses. The specimen has great color and contrast. It is positioned on a rounded piece of matrix that also includes the impression of a brachiopod. This is a fine example of a Dalmanites from the Rochester Shale.
