100 theropod dinosaur species, video

This 28 February 2019 video says about itself:

Dinosaur Size & Weight Comparison [Theropods]

Another video used to say about itself:

Theropod Dinosaur Size Comparison

The Theropoda (meaning “beast-footed”) dinosaurs were a suborder of the Saurischian dinosaurs. Dinosaurs in the Theropod suborder include, among others, Allosaurus, Spinosaurus, and Tyrannosaurus rex.

Theropods first appeared during the Triassic period, about 230 million years ago, and gradually diverged into many different lineages. At some time during the Jurassic period, or perhaps earlier, one of the lineages gave rise to the first first birds. Theropod dinosaurs survived until the end of the Cretaceous period, about 65 million years ago, when all the remaining non-avian dinosaurs became extinct, although of course birds (which technically are a type of Theropod dinosaur) survive to the present day.

Another, 29 March 2019, video used to say about itself:

Theropod Dinosaur Sizes (100 Theropod Dinosaurs from A to Z)

Theropoda/Theropod, “wild beast” is a dinosaur suborder that is characterized by hollow bones and three-toed limbs. They are generally classed as a group of saurischian dinosaurs, although a 2017 paper has instead placed them in the proposed clade Ornithoscelida as the closest relatives of the Ornithischia.

Theropods were ancestrally carnivorous, although a number of theropod groups evolved to become herbivores, omnivores, piscivores, and insectivores.

Theropods first appeared during the Carnian age of the late Triassic period 231.4 million years ago (Ma) and included the sole large terrestrial carnivores from the Early Jurassic until at least the close of the Cretaceous, about 66 Ma.

In the Jurassic, birds evolved from small specialized coelurosaurian theropods, and are today represented by about 10,500 living species.

There are more than 100 species of Theropods. In this video, I take only confirmed Theropod sizes which are common. So what is your favorite dinosaur?
