Title: Dinosaurs And Non-Dinosaurs

Alt text: Staplers are actually in Pseudosuchia, making them more closely related to crocodiles than to dinosaurs.

*bony fish

We are closer to your average fish (I don't know any specific ones) with bones than they are with sharks (non-bony, cartilage!)

Herrings, salmon/trout, cod/haddock are all bony fish.

The vast majority of extant fish are members of Osteichthyes (bony fish).

In particular, ray-finned fish are bony fish:

Actinopterygii, members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that constitutes nearly 99% of the over 30,000 living species of fish. The vast majority of extant actinopterygian species are teleosts, and by species count they dominate the subphylum Vertebrata, comprising over 50% of all living vertebrates.
