Compared
to some larger Cretaceous crocodiles
such as Deinosuchus,
Allodaposuchus was actually quite small, but it
still would have
been a serious danger to the smaller dinosaurs that were running across
Europe during the Cretaceous. Given the speed of smaller ornithopod
dinosaurs the best chance that Allodaposuchus had
of making a kill
would have been to us ambush tactics similar to those seen in
crocodiles today. Allodaposuchus may have also
scavenged the kills of
larger dinosaurs. Additionally by living in what is now the Hateg
Basin of Romania, Allodaposuchus probably would
have been in regular
contact with what are termed dwarf dinosaurs.
Back
in the Cretaceous Hateg basin was actually an island separated from
mainland Europe, and the animals living there grew smaller than their
mainland contemporaries by a process termed insular dwarfism. This is
a process where animals grow smaller as to not exhaust the limited
amounts of food plants (and by extension prey for carnivorous
animals) that are available on a smaller land mass. Allodaposuchus
might not have grown that much smaller however, as since crocodiles
are cold blooded and can reduce their metabolism they can survive for
longer upon a reduced amount of food. With this in mind the
Allodaposuchus living upon what was once Hateg
Island probably would
have been considerably higher up the food chain than Allodaposuchus
on
the mainland.
Remains
of a crocodile referred to as Crocodilus affuvelensis
were once thought
to belong Allodaposuchus, but a review by Jeremy
Martin and Eric
Buffetaut in 2008 saw these remains erected as their own distinct
genus, Massaliasuchus.
