Three New Beavers from Utah

** "Three New Beavers from Utah" by Stephen David Durrant and Harold S. Crane is a scientific work that carefully examines beaver subspecies in Utah, identifying and describing three previously unrecognized types. The book focuses on detailed analysis of these beavers, known as "Castor canadensis pallidus", "Castor canadensis rostralis", and "Castor canadensis duchesnei", carefully providing their size, color, skull structure, and where they live, comparing them to already known types. The authors stress how important it is to classify them correctly, considering possible genetic changes with solid evidence they have gathered. This contributes crucial knowledge to the understanding of beaver diversity within North America, advancing the field of mammalogy through careful observation and classification. **
