From the Trias of Diegerloch, Stuttgart. era! trao-ments of bone, differing in structure from that of the asso- ciated saurians and fish, and believed to be mammalian, were imbed- ded near them in the same rock. Xo anatomist had been able to give any feasible conjecture as to the affinities of this minute quadru- ped until Dr. Falconer, in 1857, recognized an unmistakable resem- blance between its teeth and the two back molars of his new genus Plagiaulax (see above, fig. 373, p. 383), from the Purbeck strata. This would lead us to the conclusion that Microlestes was marsupial and plant-eating. In Wurtemberg there are two bone-beds, namely, that containing the Microlestes, which has just been described, which constitutes, as we have seen, the uppermost member of the Trias, and another of still greater extent, and still more rich in the remains of fish and reptiles, which is of older date, intervening between the Keuper and Musckelkalk. The genera Saurichthys, Hybodus, and Gyrolepis, are found in both these breccias, and one of the species, Saurichthys Mongeoti, is common to both bone-beds, as is also a remarkable reptile called.
