Figure 3

DNA sequences of clones from two fragments of the chloroplast rbcL gene amplified from the three paleofecal samples. Letters and numbers to the left indicate clone number, sample number [given as A(I), B(II), C(III)], extraction number, and PCR number. G indicates samples that were ground under liquid nitrogen and extracted, and R indicates samples that were rehydrated and extracted. X indicates clones that match data bank sequences with two or more differences. j indicates clones that represent putative jumping PCR events. Sequence clusters were identified as: A, Rhamnaceae; B, Ulmaceae; C, Fagaceae; D, Asteracea; E, Liliales; F, Fabaceae; G, Solonaceae; and H, Fouquieriaceae. * indicates two clones similar to the order Zingiberales.
