_Kollikodon ritchiei_ may have been around 1m long - a very rough estimate
given that it's known only from a dentary (with some teeth still in place).
We don't have any identifiable postcranial remains, so it's impossible to
judge how specialized it was for swimming. The shellfish-eating idea comes
from the shape of the teeth, which appear suitable for crushing shellfish.
