Wild Kratts: Prehistoric

Wild Kratts: Prehistoric is a spin-off of the PBS Kids series, Wild Kratts. The series consists of the zoologist brothers Chris and Martin Kratt, along with the rest of the Wild Kratts team traveling through various geological time periods using their time machine ship and encountered dinosaurs and other prehistoric animals in each time period. Using their Creature Power of many of them, the Kratt brothers and their team witness and follow the lives of these long extinct animals and learn about them.

Plot
After traveling around the world to witness and follow the lives of any animals and protecting them from harm such as Zach and the other villains, using their Creature Power, zoologist and conservationist brothers Chris and Martin Kratt, along with their friends Aviva, Koki, and Jimmy Z, are back and this time, they are going on an epic animal mission and adventure that would take them back hundreds, thousands, and even millions of years into the past as after the main events of Wild Kratts, Aviva has created a time traveling ship that would take them into any period or era in Earth's long history and so they travel into three geological era that make up the Phanerozoic eon: Using their time traveling ship, the Wild Kratts travel to any period in prehistory, encountering dinosaurs and other prehistoric animals, and, like they did in Wild Kratts, using their Creature Power of them, they'll follow the lives of these amazing animals, learning how they live, fought, survive, nurture their young, why they became extinct, how they're related to modern animals, and how they were so successful. In addition to facing deadly, awesome predators such as Tyrannosaurus rex the King of the Dinosaurs, the Saber-toothed cat Smilodon, the armored fish Dunkleosteus, and the bizarre Anomalocaris one of the first large super predators on Earth, the Kratt brothers and the rest of the Wild Kratts team would also have to face, battle, and brave natural elements such asteroid impact events, erupting volcanoes, ice ages, and sticky tar pits. But they also have to face and battle their villainous enemies that they did in Wild Kratts: Zachary "Zach" Varmitech, a cruel robotic inventor, the sadistic Chef Gourmand, the cruel and greedy fashion-designer Donita Donata and her bumbling henchman Dabio, and the careless Pavers are planning to infiltrate the Wild Kratts' time traveling ship and planning to capture any prehistoric creature for whatever villainous deed they're doing (or in Pavers' case, wipe out any habitat to build a shopping mall or factory) and so using their Creature Powers, the brothers and their team must stop them and rescue the animals, as well as stopping them from altering the Present. So lets take a journey back in time and join along with them in- Wild Kratts: Prehistoric!
 * The Paleozoic era, the "Age of Early Life", the era when early, complex multicellular organisms such as animals and plants thrived and evolved in the oceans, giving rise to many groups (both extinct and living) and eventually moved out of the water and onto dry land (such as tetrapods) and evolved and thrived. The era was marked by two major evolutionary events from beginning to end: the Cambrian Explosion (when animal life became complex for the first time and many modern phyla's of animals evolved from a common ancestor during this event, which began around 542 million years ago) and the Permian-Triassic Mass Extinction aka the "Great Dying (when nearly all life on Earth such as 95% of all marine life and 70% of land vertebrates were wiped out in the biggest and most catastrophic mass extinction in our planet's history, 252 million years ago).
 * The Mesozoic era, the "Age of Reptiles", the time when dinosaurs and other sauropsids, big and small and both predator and prey, were the dominant animal species on land, sea, and air.
 * The Cenozoic era, the "Age of Mammals", when mammals dominated the world, giving rise to many modern animals including humans, while our planet was becoming more familiar than ever for the last 66 million years.
