The Dimetrodon first appeared in the Paleozoic era, which held the Permian period.

Dimetrodon genus (and specially the Dimetrodon limbatus species) went extinct around 40 My before the appearance of the first dinosaur during the Triassic period of the Mesozoicera.Spinosaurusgenus appeared only during the Late Jurassic.There is no possible direct genetic connection between Spinosaurus(a dinosaur therapod) and Dimetrodon (a synapsid mammelian reptil that left no descendents after the «Great Dying», the Permian mass extinction).
The Permian Period was ended by the Permian/Triassic Extinction Event, which wiped out 90% of the species on Earth at that time.

The Triassic and Jurassic periods, like the Permian and Triassic periods, are characterized by significant geological and biological developments. Both pairs mark transitions between major eras, with the Triassic serving as a bridge between the Paleozoic and Mesozoic eras. Additionally, each period experienced notable shifts in biodiversity, including the rise of dominant reptilian groups in the Triassic and Jurassic, paralleling the recovery and diversification of life following the Permian-Triassic extinction event. Both periods also witness substantial climatic changes that influenced terrestrial and marine ecosystems.
