Extinct Sand Tiger
Age - Eocene Occurrence - Common
Striatolamia macrota is one of the few species from NJ to posse moderately strong striations on the lingual side of the tooth. These teeth range in size from 1/2 inch to 2 inches plus, with the average being a little over an inch. The anterior teeth have a moderately narrow elongated crown with one small (sometimes even completely lacking), cusplet on each shoulder. The moderately strong striations tend to weaken the larger the tooth gets. There is a pronounced lingual protuberance and obvious nutrient grove on the root. The lateral teeth are broader and compressed, the striations are weaker or lacking entirely and the cusplets reduced, often appearing as no more than a scalloped nub. Although not that uncommon, these teeth are very prone to root damage.
I just like this picture.

Blades are the order of the day in the New Jersey area.
