In January 2019, I found this Smilodon gracilis partial left dentary in coastal South Carolina. I am finally uploading it because it was finally positively identified by a paleontologist last week. The m1 is complete, and the p4 is broken off, but the roots are still in the jaw fragment. This was the smaller relative of Smilodon fatalis which only had a p4 and a m1 instead of a p3, p4, and m1 on the lower dentary. Page 216 of The Fossil Vertebrates of Florida has a picture that is a perfect match. This is definitely the best find in my collection (outdoing the Dire Wolf K9 from last December).
