One of the most distinguishing features of Leptomeryx was the presence of two toes on its rear feet and four on its fore feet. It also had fang-like upper canines (probably for defense) and fed on leafy vegetation.
Because of replacement minerals, most of the fossil mammal teeth from the White River Formation of South Dakota will fluoresce to some degree. The teeth are usually replaced by calcite, which will fluoresce a yellow to yellow-orange. Any green showing up on the specimen is usually chalcedony and is usually part of the bone or bone marrow. On a few specimens there may be a bright green at the base of the specimen this will be an oil based clay holding up the specimen. Any purple on the specimen is the UV light reflecting off the light colored areas of the specimen and is not fluorescence. The fossil teeth from South Dakota will fluoresce under either long or short wave, but they fluoresce best under both at the same time. You may see a photo of some of the specimens under normal light by returning to the main fluorescent page and clicking on the link "to view specimen material from South Dakota." You may also view all teeth by going to the fossil teeth page and then to the appropriate page for the teeth you want to view. The item number will be the same as the number in the fluorescent section without the "F" at the end of the number.
Specimen is mandibular teeth.
