A Systematic Study on Tooth Enamel Microstructures of Lambdopsalis bulla (Multituberculate, Mammalia) - Implications for Multituberculate Biology and Phylogeny
Fig 2
Enamel prism shape in different teeth of Lambdopsalis bulla.
Cross-sections of (A) Left M2 (V 20298.7) and (B) Left M1 (V 20298.5) showing true outline of the sheath and shape of the seam; (C) The prism shape of the right di (V 20300.1); (D) Prisms of right m1 (V 20299–3) in insufficiently acid prepared section; E-H. Distortions of the prism shape caused by the cutting plane with an angle to the long axis of the prisms in the enamel of right I2 (V 20298.3), right m1 (V 20297.5), right p4 (V 20299–4) and right M2 (V 20298.8). All pictures are SEM-images except B, which is an optic image. Abbreviations: EDJ: enamel dentine junction; I: interprismatic matrix; OES: outer enamel surface; P: prism; S: sheath; Sm: seam; T: tubule.
