“…Crocodilians are not alone in providing climate information. Other vertebrates, especially mammals, have received considerable attention (Colbert, 1953(Colbert, , 1964aEsteban and Sanchiz, 1986;Schleich, 1986;Thackeray, 1987;Janis, 1989Janis, , 1993Repenning, 1990;Uhen, 1992;Woodcock, 1992). Moreover, since Lyell (1830), most geologists have recognized the palaeobotanical record as being the most informative for reconstructing terrestrial palaeoclimate (De Martius, 1825;Lyell, 1830;Nathorst, 1912;Seward, 1892;Wolfe, 1971 ).…”
