| Crab fossils were found within the lowest portion of the exposed Bahariya Formation in a blue-gray indurated shale. |
| The rocks consist of arenaceous, pebbly sediments which have been indurated, folded and faulted with high grades of metamorphism in places. |
| With difficulty, the crust can be removed to reveal an indurated ulcer that may be red, swollen and oozing with pus. |
| The rocks have been intensely deformed and sheared and the calcareous conglomeratic sandstones are well indurated. |
| The cephalic end of the worm produces an indurated papule that vesiculates and eventually ulcerates. |
| Examination of the gastrectomy specimen revealed an indurated tumor with central ulceration located in the fundus. |
