Vertebrates came first... all of those other creatures are vertebrates.. prior to the evolution of the spine (vertebrae) there were no fish, reptiles, mammals birds... nothing like them..
First were the plants and fungi, then came the arthropods, then finally the vertebrates.
Amphibians were the first vertebrates that came out of the water. The first vertebrates that could live outside of the water though were reptiles. or class reptilia this was during the Carboniferous period.
The first land vertebrates appeared in the: Devonian
After fish, amphibians were the next group of creatures to evolve on Earth. Amphibians are cold-blooded vertebrates that can live both on land and in water. They were the first vertebrates to colonize terrestrial habitats.
They were the original form of life and they came before vertebrates.
Fish
No. The 1st vertebrates appeared in the fossil record about 525 million years ago during the Cambrian Period. This was in the Paleozoic Era.

Dinosaurs
The phylum Chordata is most closely related phylogenetically to the first vertebrates. Chordates share a number of characteristics with vertebrates, such as having a notochord, dorsal nerve cord, and pharyngeal slits. Cells within the notochord further develop into the vertebrae that define vertebrates.
