Breviparopus (ichnotype B. taghbaloutensis) is the name given to an ichnogenus of dinosaur, having been made by an unknown genus of sauropod. As an ichnogenus, the taxon is represented by (and named for) a 90-metre (295 ft) long series of fossil tracks, or ichnites , found in the spring of 1979 in the Atlas Mountains of present-day Morocco .
Argentinosaurus (meaning "lizard from Argentina") is a genus of giant sauropod dinosaur that lived during the Late Cretaceous period in what is now Argentina.Although it is only known from fragmentary remains, Argentinosaurus is one of the largest known land animals of all time, perhaps the largest, measuring 30–35 m (98–115 ft) long and weighing 65–80 t (72–88 short tons).
Sexual dimorphism in dinosaurs refers to the different physical characteristics of male and female dinosaurs of the same species. This means that the male and female dinosaurs of a species may differ in size, color, shape, or they may even look like a completely different species altogether, such as in the case of the anglerfish.
In the theropod lineage leading to birds, body size shrank continuously over a period of 50 million years, from an average of 163 kilograms (359 lb) down to 0.8 kg (1.8 lb). This was the only dinosaur lineage to get continuously smaller over such an extended time period, and their skeletons developed adaptations at about four times the average ...
The proportions of its body were somewhat similar to those of diplodocoids, likely through convergent evolution: Brachytrachelopan: 2005 Cañadón Calcáreo Formation (Late Jurassic, Oxfordian to Tithonian) Argentina: Possessed the shortest neck of any known sauropod Brasilotitan: 2013 Adamantina Formation (Late Cretaceous, Maastrichtian) Brazil
