Plants during the beginning of the Mesozoic (the era when dinosaurs existed), included conifers and tree ferns. At the end of the Triassic, cycads and then ginkgos evolved. All of the above were the primary plants throughout the rest of the Mesozoic, except ginkgos which began to decline in the early Cretaceous. At the beginning of the Cretaceous, the first flowering plants evolved. Before the end of the Mesozoic, there were already Magnolids (trees that include magnolias) and palms.
Many of the same groups of animals that exist today coexisted with dinosaurs. Insects like roaches and dragonflies existed alongside dinosaurs, and termites and ants evolved in the Jurassic. Wasps and bees evolved during the early Cretaceous. Small mammals evolved during the Mesozoic, and birds evolved from dinosaurs in the early Cretaceous. Frogs and salamanders, as well as turtles, first appeared in the Jurassic, and modern crocodillians appeared in the Cretaceous. Some extinct animals that coexisted with dinosaurs include icthyosaurs, plesiosaurs, pterosaurs, huge amphibians like Koolasuchus, mosasaurs, and fully marine crocodilymorphs called thalattosuchians.
The dinosaurs existed as they evolved best to fit the ecological niches of the day.
Yes. Spinosaurus was a real dinosaur that existed millions of years ago, along with all of the other dinosaurs.
Like all other animals on the planet (that I know of) have existed since the dinosaurs died out the Eagle is a medieval animal.
177,000,000 years ago ate other sea dinosaurs
Pterodactyls died out along with the dinosaurs and many other animal and plant species during the K-T extinction event. It is believed that an asteroid, along with other environmental changes, struck the Earth and contributed to the mass extinction. Dinosaurs, pterosaurs, and many marine reptiles were not able to cope, so they went extinct.
Dinosaurs existed. We're not too sure if dragons did. In other words, Dragons exist in the "mind" Dinosaurs exist in the museums. Dragons also exist in literature and in scuplture. Not all dinosaurs are extinct.

A pug!
Nigersaurus lived in Niger and other parts of North Africa. It may have lived along side dinosaurs like Carcharodontosaurus, Spinosaurus, Paralititan, and other dinosaurs.
Nothing, Blue Whales are the biggest creatures on Earth
Fish.
Parasaurolophus died off at the end of the Cretaceous period along with all the other dinosaurs.
