Trilobites: Isotelus
The best trilobite find of the day as this almost perfect, enrolled Isotelus.
Nice!
Another enrolled Isotelus that was found, was much smaller. But still
impressive at any size.
Lots of Isotelus
trilobite fragments were found. Most notably, a number of hypostomes (mouth
plates) were found (below two).
Here's a large pair of thorax segments from an Isotelus
Trilobite.
And glabella (head) fragments of Isotelus, showing the eye. were also
found.
And what field trip would be complete withouth Pygidia (tail plates) of the Isotelus
trilobite! (below).
While the Isoteus Trilobite is the Ohio state fossil, other states were
represented too, as shown below, by this rock, clearly from
Oklahoma! (upside-down)
