Named By: Flannery, Archer, Rich & Jones - 1995.
Classification: Chordata, Mammalia, Monotremata, Platypoda.
Species: K. ritchiei (type).
Diet: Carnivore, possibly durophagous.
Known locations: Australia, New South Wales, Lightning Ridge - Griman Creek Formation.
Time period: Albian of the Cretaceous.
Fossil representation: Partial dentary (lower jaw) and two molar teeth.
Kollikodon shares four things with another monotreme called Steropodon. One is that they were both related to the modern day platypus. Two is that they are both known from the same fossil formation. Three is that both of these genera have been described only from partial jaw bones. Four is that both of these jaws have been opalised (Turned to opal, a process that is not that uncommon for Australian fossils). The similarities are so great it would be tempting to think that they could be the same creature, but study of the teeth and their form has confirmed that they are indeed two separate genera. The teeth of Kollikodon are seen as being particularly well adapted for crushing shellfish, something that hints at a durophagous diet.
