| 11. | Stahle and Matthew D . Therrell, a fellow dendrochronologist, started taking test borings.
|
| 12. | "We've already been out there doing test borings and drawing building permits.
|
| 13. | State engineers collected 135 samples from more than 46 soil borings between May and August.
|
| 14. | The first experimental borings at the site began in 1902, and continued until 1908.
|
| 15. | Macrobioerosion, which produces borings visible to the naked eye, shows two distinct evolutionary radiations.
|
| 16. | Their club-shaped borings are given the trace fossil name " Gastrochaenolites ".
|
| 17. | The station was built on an plot of land acquired as a result of tidal borings.
|
| 18. | Some of the petrified wood at this site bear the borings made by ancient ship worms.
|
| 19. | The depressions are not symmetrical enough for gastropod drill marks and are not shaped like sponge borings.
|
| 20. | We had a structural engineer do borings into the footings, and we had to add support there,
