       A relative of the famous Tyrannosaurus,‭ ‬Dynamoterror lived further south in what is now the New Mexico area of the USA.‭ ‬Described after a pain staking process of re-combined the partial remains of the holotype,‭ ‬Dynamoterror was revealed to have been a medium/large nine meter long predatory dinosaur.‭ ‬This is smaller than the largest known tyrannosaurs,‭ ‬but certainly a comfortable average for most tyrannosaurs in North America during the Campanian stage of the Cretaceous.‭ ‬Dynamoterror is at the time of its writing one of the oldest members of the‭ ‬Tyrannosauridae in North America.‭
       Dynamoterror is known to have lived in the same habitat as armoured nodosaurid dinosaurs such as Invictarx.‭ ‬It is possible that at times Dynamoterror attacked these dinosaurs,‭ ‬and probably other kinds that we have yet to discover.‭ ‬Dynamoterror however was‭ ‬not the only large predator in the area that it lived.‭ ‬Fossil remains from the same fossil bearing formation as Dynamoterror have also been attributed to the giant crocodile Deinosuchus.‭ ‬Fossil remains from other locations have shown that‭ ‬these massive crocodiles had no fear of lashing out at tyrannosaurs.
       Another early tyrannosaur that lived in North America at the same approximate time as Dynamoterror is Lythronax,‭ ‬while the genus Bistahieversor is also known from New Mexico,‭ ‬but from a different fossil bearing rock formation.
