Thresher (Paranomotodon angustidens)
Age – Late Cretaceous; Commonality – Uncommon; Size – ¼ – ¾ inches
Thresher shark teeth are somewhat ignored by collectors, probably because their features are worn down easily by stream action, which causes them to be mistaken for a worn goblin, porbeagle, or sand tiger. Nice threshers are hard to come by. The crown is similar to Archaeolamna kopingensis teeth. The thresher crown is less robust and is thinner on the carinae. Thresher teeth have small vestigial cusplets, which look like small bumps on the shoulders of the tooth. They are almost like extensions of the crown. The thresher roots are slightly porous and have a large nutrient groove. The anterior tooth crowns are straight and the laterals are angled distally. The upper teeth are generally flatter and less robust than the lowers.
