Poebrotherium means grass eating beast. Early camels did not have a hump, like today's camels, but more closely resembled present day alpacas and llamas and are likely related to them. They were, perhaps, two feet tall and weighed 50 pounds (roughly the size of modern sheep). They are fairly rare. In spite of the fact that it is named "grass eating beast," it is likely that its diet was either a browser or a mixed feeder and that grass probably played a minimal role.
The Poebrotherium skull is approximately seven inches long. The skull is long and thin. Because of this complete skulls are very rare. Teeth near the front of the jaw are smaller in size and peg like and more adapted to plucking while those farther back are more adapted for grinding. The peg like teeth would have been located in the premaxilla. The three premolars and three molars would have been in the maxilla.
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 premaxillary molar teeth.
