Tyrannosaurus rex teeth found in public digs break records
August 23, 2017
BISMARCK, N.D. (AP) — Participants in a public fossil dig south of Bismarck last week found two large Tyrannosaurus rex teeth, each of them setting records for the North Dakota Geological Survey.
Officials say the first tooth measured about 2.5 inches long. The second tooth, found less than an hour later and only a few feet from where the first tooth was round, measured 4.5 inches long.
The teeth were the ninth and 10th ones discovered from the dig site in the last three years. Casts of the teeth will be on display in Bismarck's Heritage Center in the coming weeks.
