The exact number of cells in dinosaurs is not known, as it varies widely among species and sizes, similar to modern animals. For example, a small dinosaur might have millions of cells, while a large dinosaur like a sauropod could have billions. Cells in dinosaurs, like in other vertebrates, would have included various types such as muscle, bone, and nerve cells. Overall, the total cell count would depend on the specific dinosaur and its size.
Considering that most eukaryotic cells have mitochondria and that dinosaurs are eukaryotes like all other animals that ever lived, it is certain that they did have mitochondria in their cells. In fact, birds are considered dinosaurs (they certainly descended from dinosaurs) and their cells have mitochondria, so we can be as sure as scientifically possible that dinosaurs indeed did have mitochondria.
Dinosaurs were endotherms
Dinosaurs had cells similar in size to modern-day animals like us. The size of cells doesn't change much across species, but the number of cells in an organism can vary greatly. For example, ants have smaller bodies with more cells compared to us, which is why they are much smaller in size.
When the dinosaurs lived there were sea monsters but they were called marine reptiles and were not dinosaurs.
The number of cells in a dinosaur, like in modern animals, would vary significantly depending on the species and size. For instance, small dinosaurs might have millions of cells, while larger ones could have billions or even trillions of cells. Similar to today's reptiles and birds, dinosaurs would have had complex cellular structures to support their bodily functions. However, without direct fossil evidence to count cells, it's impossible to provide an exact number.

Yes. All birds are direct descendants of dinosaurs and are considered by many to be dinosaurs.
there where many species of dinosaurs some of them still might not have been discovered yet
Birds are direct descendants of dinosaurs and are considered by many to be dinosaurs. Birds emerged in the later Jurassic period, branching of from a group of dinosaurs called theropods, two legged animals that accounted for all carnivorous dinosaurs. Many theropod dinosaurs show birdlike traits (including feathers on many species), particularly dromaeosaurs such as velociraptor.
Yes. Many scientists nowadays consider birds to be dinosaurs. Animals such as pterodactyl were not actually dinosaurs.
