No! Although this is a common mistake, all dinosaurs were land animals. All animals that lived in the sea at the same time as the dinosaurs weren't actually classed as dinosaurs even though they have similarities :)
When the dinosaurs lived there were sea monsters but they were called marine reptiles and were not dinosaurs.
No dinosaurs lived in the sea. There were other reptiles that adopted a marine life, but those weren't dinosaurs.
California was under a shallow sea during the time that dinosaurs lived. Dinosaurs lived on land, so none lived in California.

There are no names of underwater dinosaurs because there were no underwater dinosaurs. Sea reptiles that lived at the same time as the dinosaurs were around. Names of these sea-living reptiles include: Liopleurodon, Opthalmosaurus and Tylosaurus.
No dinosaurs lived in the sea. At the same time as the dinosaurs, there were OTHER CREATURES that adopted a pelagic lifestyle. These included Giant turtles, like Archelon, Icthyosaurs ("fish lizards") and Mosasaurs, probably as close to "sea serpents" as the world has ever gotten, as well as the long-necked Pleisosaurs, which did look rather like dinosaurs with flippers, but none of these were actually dinosaurs.
Dinosaurs lived everywhere. You don't necessarily need a map to find out where dinosaurs lived.
Animals of the Ice Age lived after the dinosaurs.
dinosaurs lived for about 250 million years ago.
Dinosaurs lived during the Mesozoic Era.
A number of dinosaurs are known from the Tendaguru Formation of Tanzania. Kenya may have been covered in a shallow sea at the time, but if it wasn't, the dinosaurs in Tanzania and Kenya would have been the same. These include Kentrosaurus, Giraffatitan, Dysalotosaurus, Dicraeosaurus, Allosaurus, Ceratosaurus, and Elaphrosaurus. They lived around 150 million years ago.
Marine reptiles were not technically "dinosaurs" but some were exceptionally large, such as the pliosaurs, pleisosaurs, icthyosaurs, and mososaurs. These included: Archelon - giant turtles Askeptosaurus - giant eels Ichthyosaurus - giant fish-like creatures Liopleuradon - one of the largest Mosasaurus - one of the first identified from a fossil, a snakelike sea lizard Stomatosuchus - 36-foot prehistoric crocodile remarkably similar to modern species Tylosaurus - a sleek 50-ft swimming predator (see the related link for others)
