It is hard to say what animal group was the most successful during the Mesozoic. However, reptiles were the so called "dominant" animals. Dinosaurs lived on land, pterosaurs flew through the air, and plesiosaurs, icthyosaurs, and mosasaurs were some of the largest creatures in the oceans.

Out of all the creatures, the most successful group would probably be the reptiles because they so heavily populated the earth at that time.
Dinosaurs were the most successful group of animals during the Mesozoic era, dominating terrestrial ecosystems for millions of years. They evolved into a diverse range of shapes and sizes and were the top predators in many environments. The Mesozoic era also saw the rise of flowering plants and the expansion of marine reptiles.

The dominant land animal life during the Mesozoic was reptiles and dinosaurs.However, it is important to note that dominant does not mean the most biodiverse, common, or consisting of the greatest biomass. It simply means that they were the most common large vertebrates. Insects, for example, have always beaten reptiles in biodiversity and I believe biomass, too.
During the Mesozoic Era, most mammals were small, nocturnal, and likely insectivorous. They were overshadowed by larger reptiles like dinosaurs and did not become the dominant group of animals until after the extinction of the dinosaurs at the end of the Mesozoic.

Dinosaurs: These were diverse group of reptiles that dominated the Mesozoic era. Mammals: Though small and insignificant at the time, mammals began to diversify and evolve during the Mesozoic era. Birds: Birds evolved from small theropod dinosaurs and became prominent during the Mesozoic era. Marine reptiles: Creatures like ichthyosaurs, plesiosaurs, and mosasaurs were prominent marine reptiles during this era.
