Niether. Pliosaurus wasn't even a dinosaurs. It was a Plesiosaur.
Birds are believed to have evolved from theropod dinosaurs during the Mesozoic era. The fossil record shows a gradual transition from small, feathered dinosaurs to early bird species, which eventually led to the wide diversity of bird species we see today.
compsognathus is the smallest dinosaur and is the size of a chicken, but palaeontologists have just discovered 'micropachycephalosaurus' which might be even smaller and has the longest name of any dinosaur so far!
The largest herbivorous dinosaur was the Argentinosaurus. This dinosaur lived during the Late Cretaceous period and could reach lengths of up to 100 feet and weigh up to 100 tons. It is considered one of the largest land animals to have ever existed.
Some dangerous dinosaurs that lived during the Jurassic period include Allosaurus, a large predatory theropod dinosaur, as well as Ceratosaurus, Dilophosaurus, and Torvosaurus. These dinosaurs were apex predators and hunted other animals for food.
The first birds appeared during the Jurassic period, around 150 million years ago. They are believed to have evolved from small theropod dinosaurs.
The rare British sauropod Gigantosaurus may have been 70 feet long. The Argentine theropod GiganOtosaurus was 45 feet long.
Stegosaurus is an ornithischian dinosaur, belonging to the order Thyreophora. Tyrannosaurus is a tyrannosaurid theropod dinosaur. Brachiosaurus is a sauropod dinosaur.
The theropod individuals we know of that lived the longest lived less than 30 years. The longest sauropod lifespans we know of were about 30 years, as well.
To date, the largest sauropod found is Argentinosaurus, of Patagonia, literally the Land of Giants. Being the largest sauropod, it was the largest dinosaur, living alongside the largest theropod in the world, to be determined. Argentinosaurus measured 36.6 metres in length and weighed in at roughly 100 metric tonnes. There are rumors of an even larger saropod, up to 200ft long, but the only remains were destroyed.
Yes, Apatosaurus is a sauropod.
The longest known lifespan of a theropod was under 30 years. The longest known lifespan of a sauropod was just over 30 years. Other large dinosaurs probably had similarly short lifespans.
Sauropod translates as "lizard foot."
A sauropod can live up to 100 years of age.

Yes, the Allosaurus was a large theropod, a carnivorous dinosaur.
In England, notable dinosaurs include the large theropod Megalosaurus and the armored dinosaur Hypsilophodon. Finland's fossil record is limited, but dinosaur footprints and some fossils suggest the presence of small theropods. Italy is known for the discovery of dinosaurs like the giant sauropod Tarchia and the theropod Dromaeosaurus. These regions provide crucial insights into the diversity of dinosaurs across Europe during the Mesozoic era.
