EXPLANATION OF PLATES. 



[All figures nearly natural size]. 



Plate XXXVI. 



Fig, L — Clay model, showing incisions made with the upper 

 and lower premolars of Thylacoleo. 



Fig. 2. — Section of the head of a femur, showing fine chisel- 

 like incisions. Pejark Marsh. 



Fig. 3. — Piece of a lini'b bone, w4th ci^rved incisions. Salt 

 Creek, Normanville, S. Australia. 



Fig. 4. — Fragment of bone, with straight incisions. Salt 

 Creek, Normanville, S. Australia. 



Fig. 5. — Longitudinal sectional of a calcaneum, with curved 

 incisions, and a serrated edge where a pointed 

 tooth has penetrated and split the bone. Salt 

 Creek, Normanville, S. Australia. 



Fig. 6. — Shaft of a metatarsus, witli curved incisions made 

 by the lower premolar of Thylacoleo. The end 

 Avhere they occur has been fractured transversely 

 by means of one of these incisions, as seen by 

 the similarity of the curves. Queensland. 



Fig. 7. — Small fragment fractured by a curved incision, like 

 that of Fig. 6. An incision having a similar 

 curve occurs close to the fracture. Pejark Marsh. 



Fig. 8. — Small piece of large limb bone, showing how a tooth 

 has penetrated the bone to a slight depth, and 

 then pared off its surface in a broad shallow^ 

 groove. Pejark Marsh. 



Fig. 9. — Gash incisions. Salt Creek, S. Australia. 



Fig«. 10, 11. — Cash incisions. TTie oblique terminal fractures 

 are evidently due to such incisions. Pejark 

 Marsh. 



Fig. 12. — Proximal phalanx of the 4th toe of a large extinct 

 kangaroo, showing a piece broken away by the 

 entry of a pointed tooth, leaving thereby a jagged 

 edge. Pejark Marsh. 



Fig. 13. — Longitudinal section of the underside of a phalanx 

 similar to Fig. 12. Pejark Marsh.
