On a model mechanism for the spatial patterning of teeth primordia in the Alligator [PDF]
, 1996 We propose a model mechanism for the initiation and spatial positioning of teeth primordia in the alligator,Alligator mississippiensis. Detailed embryological studies by Westergaard & Ferguson (1986, 1987, 1990) show that jaw growth plays a crucial role ...
