They both have a notochord, which qualifies them as chordates.

Reptiles and birds share enough common characteristics to be classified in the same clade called Sauropsida, which includes all modern reptiles and birds.
Humans, birds, and fish all have a notochord that is replaced by a vertebral column as the body develops.
Freshwater and saltwater fish are in the same phylum that we are, and reptiles and amphibians and birds are in; phylum chordata, subphylum craniata, subphylum vertebrata.
No they cannot. In biological classification, the family comes after the class. Basically that means that the family is more specific than the class so two animals that are in the same family may not necessarily be in the same class.
No. Dinosaurs and trilobites are completely different. Trilobites were arthropods in the same phylum as insects and crustaceans. They went extinct before the first dinosaurs appeared. Dinosaurs are vertebrates and are technically classified as reptiles, though they had more in common with birds.
Moths are arthropods because they have jointed legs and a chitin exoskeleton and birds are chordata because they have a backbone and nervous system.
Obviously NOT!Insects are classified as:Kingdom:AnimaliaPhylum:ArthropodaSubphylum:HexapodaClass:InsectaRats are classified as:Kingdom:AnimaliaPhylum:ChordataClass:MammaliaOrder:RodentiaSuperfamily:MuroideaFamily:MuridaeSubfamily:MurinaeGenus:RattusSo while rats and insects are both of the kingdom Animalia, they are not even the same Phylum, much less Class.
