This week’s Fossil Friday is the subject of a paper recently published by former PCP PIRE Post Doc Aaron Wood and Spring 2013 field intern Nicole Ridgwell. The specimen is a right first or second lower molar of a chalicothere (Family Chalicotheriidae), which are an extinct group of clawed perissodactyls. The molar, collected by one of the authors of the paper, Nicole Ridgwell, was found in the Las Cascadas Formation in the Lirio Norte area of the Panama Canal. It is early Miocene in age and is the first record of a chalicothere from Central America.
