| A pair of ciliated epaulettes on each side of and behind the ciliated ring is very characteristic of some echinoid larv. |
| In the echinoid gene order, the tRNA gene cluster follows the putative control region. |
| Bioclasts are composed of benthic foraminifera, various-sized bivalve fragments, radiolaria, echinoid fragments, bryozoa and pelagic fossils. |
| Despite the astonishing abundance of echinoid spines in the coral reef horizon, echinoid tests were not found here. |
| The occurrence of the sand dollar echinoid Periarchus lyelli in the Upper Eocene Caddell Formation of Texas is confirmed. |
| The gastropod assemblage suggests an Albian age and the echinoid assemblage reportedly indicates a late Albian age. |
