| 41. | The ossicles, minute calcareous plates embedded in the skin and characteristic of each species, can include wheel and anchor shapes.
|
| 42. | The larger osteoderms are also ordered in transverse rows but are not fused into bands; small ossicles connect the larger elements.
|
| 43. | Members of the family are characterised by a complex ring of calcareous ossicles arranged in a tube, making a mosaic pattern.
|
| 44. | Spines are ossicles that project from the body wall and articulate with other ossicles through ball and socket joints mounted on tubercles.
|
| 45. | Spines are ossicles that project from the body wall and articulate with other ossicles through ball and socket joints mounted on tubercles.
|
| 46. | Petrographic analysis of marble collected from about found it to consist as much as five percent of the ghosts of recrystallised crinoid ossicles.
|
| 47. | In ophiuroids, the calcite ossicles are fused to form armor plates which are known collectively as the " test ".
|
| 48. | The tiny auditory ossicles of the middle ear and associated areas were also well preserved in this " Castorocauda " fossil.
|
| 49. | With Ernst Gaupp, he was co-architect of the Reichert Gaupp theory concerning the origin of mammalian ossicles of the ear.
|
| 50. | The most modern species are not heavily armored but they have many smaller ossicles, or small bones, found in the dermis.
