TootJi-marks of Thylacoleo. 121 



Fig. 14. — Longitudinal section of the left ramus of a kangaroo 

 jaw, through the teeth sockets. A curved frac- 

 ture has been made at a slightly oblique angle 

 across the proximal end. Pejark Marsh. 



Figs. 15, 16. — Fragments of limb bones, with forked termina- 

 tions. A type of fracture which might be due 

 to any sufficiently powerful carnivorous animal. 

 Pejark Marsh. 



Fig. 17. — Chewed bone, with about half of the surface removed. 

 The exposed area is covered with small chisel-like 

 incisions. Pejark Marsh. 



Plate XXXVII. 



Fig. 1. — Fragment of a large bone bearing an oblique curved 

 cut across one corner. On the coiner opposite, 

 a series of scallops are imperfectly indicated- 

 Pejark Marsh. 



Fig. 2. — Fragment of a limb bone, with one of its corners 

 sliced off by an oblique curved cut. Pejark 

 Marsh. 



Fig, 3. — Clay model, illustrating how curved cuts may be 

 produced by the lower premolar of ThylacoleG. 



Figs, 4, 5, 6. — Pieces of limb bones with similar oblique curved 

 cuts, but passing through the bone at more up- 

 right angles than in the case of Fig. 2. Pejark 

 Marsh. 



Fig. 7. — Concave and convex fractures, producing a pointed 

 fragment. The convex fracture is due to the 

 entry of pointed teeth penetrating the bone, both 

 from above and below ; the concave fracture may 

 have originated from an incision in the broad 

 end of the bone. Pejark Marsh. 



Figs. 8, 9. — Pieces of limb bones margined by a series of cuts 

 (or in part by fractures produced by incisions). 

 Pejark Marsh. 



Fig. 10. — Bone pointed by two obique cuts. The left-hand edge 

 also appears to have been sliced off. Pejark 

 Marsh.
