Distribution
editHistory & classification
editCarpolithes dentata specimens collected during the 1888 expedition to the Stump lake area were listed as included in the Redpath Museum collections by John William Dawson (1890).

editUndescribed Palaeocarpinus fossils
editIn the material collected by Lawrence Lambe's 1908 collecting expedition though central British Columbia, David P. Penhallow reported additional Carpolithes dentata fossils. Penhallow deemed the three Horsefly, two Quilchena, and two or three Tranquille River fossils as all equivalent to Dawsons original Carpolithes dentata specimen. In total between seven and eight additional fossils were noted, but have been largely ignored since the original mention by Penhallow.[2]
