Evidence for Turtle Evolution? | Bergman, J; Frair, W. 2007.
JC 21(3):24-26. CELD ID 19401Abstract The fossil record is rich with many well-preserved turtle shells and a wide variety of turtles 'dating back' to before dinosaurs in the Triassic. Phylogenetic analysis of turtles has resulted in much controversy and conflicting results that vary depending on the techniques used. Molecular evidence also contradicts previous evolutionary classifications based on gross morphological comparisons. The extant evidence shows that turtles appear in the fossil record fully formed.
