Not a Dino! Still a Bad-Ass Prehistoric Killer!
Dimetrodon is an extinct genus of non-mammalian synapsid that lived during the Cisuralian, around 295–272 million years ago. It is a member of the family Sphenacodontidae. The most prominent feature of Dimetrodon is the large neural spine sail on its back formed by elongated spines extending from the vertebrae.

It lived 295 to 272 million years ago, during the Early Permian. Most of the known fossils have been found in Texas, USA. Around 3 metres in length, it was one of the dominant land predators at the time. The neural spine sail may have been for thermoregulation, but is also thought to have been used for mating displays. The early synapsids, such as this pelycosaur synapsid, are sometimes described as mammal-like reptiles.Image Credit: Masato Hattori (http://masahatto2.p2.bindsite.jp/index.html)

The Big Boy! Giganotosaurus!
Giganotosaurus was one of the largest meat-eating dinosaurs. Today, Giganotosaurus is believed to have been slightly larger than T. rex, though even Giganotosaurus ranks behind Spinosaurus in size among the meat-eating dinosaurs.

Carnotaurus (meaning "meat eating bull") was an extinct genus of large theropod dinosaur which lived in South America during the Late Cretaceous Period. It is a relative of other theropod dinosaurs such as Abelisaurus, Majungasaurus, Ceratosaurus, and Rajasaurus.

Meet Majungasaurus (/məˌdʒʌŋɡəˈsɔːrəs/)
The Mahajanga (district on the northwest coast of Madagascar) Lizard!
It is unknown if Majungasaurus actively hunted their own kind or only scavenged their carcasses. However, some researchers have noted that modern Komodo monitors sometimes kill each other when competing for access to carcasses. The lizards will then proceed to cannibalize the remains of their rivals, which may suggest similar behavior in Majungasaurus and other theropods.
