seems to be yet another genus of giant titanosaurian
from South America, a continent that is now famous for the presence
of such dinosaurs. The full length of Notocolossus
speculative, but with an upper arm bone measuring 1.76 meters in
length, it is fairly safe to say that Notocolossus
would have been
easily about the twenty-five meter long mark. This could be just as
well as South America at this time is known to have also had very large
predators such as carcharodontid
theropod dinosaurs such as
roaming about at this time as well.
In the initial 2016 description of the genus, Notocolossus was treated as a sister species to Dreadnoughtus which was named in 2014.
