Ambyploda (Extinct Herbivorous Mammals)

Skeletal components of the now obsolete Order of extinct mammals the Amblypoda showing:  Coryphodon skulls (1 & 2), feet (3 & 4) and cheek teeth (5 & 6); Dinoceras skulls (7 & 8), feet (9 & 10) and cheek teeth (11 & 12).  Note the similar structure of the feet which was incorrectly used to define this obsolete group (ambly – dull or blunt; poda – feet) from fossil evidence.

Canis lupus

Canis lupus is most commonly referred to as the wolf.  With 39 subspecies the morphological variation amongst members of this species is in some ways subtle, asthetically it is diverse.  The sub-species commonly referred to as the domesticated dog (Canis lupus familiaris) is most probably derived from the more ancient lineage of asiatic/arab wolf (Canis lupus arabs).
