MEANING OF JAGUAR AND LEOPARD ROSETTES in 



platelets, like those of Fig. 61 (), (b\ (c\ (g). The form of these 

 bone-rosettes varied not only in different species, but also in the 

 same individual. 



In the Natural History Museum, besides the Great Glyptodon, 

 there are fragments of the carapaces of other species, as shown in 

 Fig. 62.

FIG. 61. Bone-rosettes of various Glyptodonts (reduced) : (a) from carapace of Glypotodon 

 asper; (b) from front, and (c) from back of head-shield of ditto (Natural History Museum) ; 

 (d) from G. Clavipes ; (e) from G. ornatus ; (/ g and ti) from other Glyptodonts in the Royal 

 College of Surgeons ; (i) groups of tail plates of a Glyptodont (Natural History Museum). 



Then in the museum of the Royal College of Surgeons there 

 are remains of other forms of Glyptodonts, with bone-rosettes 

 which perhaps are still more suggestive. In Fig. 61 (d) t (e\ (/), 

 (<")> W> some of these rosettes are shown. 



As these bone-rosettes 1 are taken from fossil remains, the 

 edges of the component plates, and in some cases their surfaces, 



1 In the Natural History Museum, the plates of the Carapace of the Glyptodon and 

 Armadillo are called 'ossification of the derm.'
