CONTINUOUS AND DISRUPTIVE DENTAL GROWTH LINES ON MOSASAUROID REPTILES (SQUAMATA) FROM THE PARAÍBA BASIN (BRAZIL)

Description

Measurements of teeth enamel thickness and spacing between growth lines in three specimens of mosasaur from Paraiba Basin, Brazil

Steps to reproduce

Each tooth was embedded in transparent polyester resin and let to dry in a vacuum chamber. Then, a mid-cross section was made on each specimen, with the aid of a diamond saw. In addition, we performed a longitudinal cross-section. After being sectioned, the specimens were polished to an ideal point in which the saw scratches were no longer visible, then glued to glass slides with resin. Finally, the specimens were cut into thin slices and polished until reached ideal thickness for visualization in microscope.
