@llundgren, @matthew-croxton, @egardner, @jeanette-pirlo For my trilobite it was Ceraurinus icarus. John’s little trilobites were Primaspis but I don’t recall the species name Brenda used. The trilobite that Tom Johnson had was some species of Isotelus – maybe maximus or gigas or maybe neither. Don’s Silurian trilobite from Indiana was a Calymene of some sort. His Moroccan one is Wallicerops but I don’t know the species (and yes, it is real). Matthew’s enrolled trilobite was a Flexicalymene retrorsa from Mt Orab. Matthew’s trace fossil is a type of “cruziana” which is a morphological descriptive term not a genus or species. This is a trace of some critter moving through the sediment going from here to there.
