| Some Teleosteans, like Diodon hystrix, have scales with triradiate roots from which arise long sharp spines directed backwards. |
| Columella with three or four triradiate verticils, as long as the slender pyramidal horn. |
| Progressive disease can produce acetabular changes, such as early triradiate closure, bicompartmentilization, and ischium varum. |
| We investigated the results of combined acetabular fractures that were treated through the extensile triradiate approach in this study. |
| The sample yielded predominantly round and triangular spores with triradiate marks and the algal cysts Tasmanites. |
| Columella straight, with two or three triradiate verticils of horizontal lateral branches, which are inserted in the shell-wall. |
