SUMMARY:
- Liopleurodon was a giant marine reptile from the family of short-necked plesiosaurs. This species lived during the Callovian stage of the Middle Jurassic Period. The typical size of a Liopleurodon varied from 16 to 23 ft, but the largest reached over 33 ft.
- Arthropleura lived in the territories of current northeastern North America and Scotland about 315 million years ago. The species ranged from almost one to 7 ft in length and were around 2 ft in width. Arthropleura's body was apparently composed of around 30 jointed segments covered by 2 side plates and one center plate.
- Megalania is the biggest monitor lizard you can possibly imagine. The youngest of its fossils dates back to approximately 50,000 years ago. The length of the largest Megalanias reached around 23 ft with a maximum weight of 1,320–1,370 lb. They were unbelievably active hunters.
- Dunkleosteus became extinct about 358–382 million years ago during the Late Devonian period. However, there wasn't just one Dunkleosteus — there were actually 10 species of it, including D. terrelli, D. denisonii, and D. magnificus. D. terrelli, the largest of them, was almost 20 ft long. Most Dunkleosteus fossils were found in North America, Poland, Belgium, and Morocco.
- Jaekelopterus was a giant predatory sea scorpion Scientists confirmed that Jaekelopterus reached a size of nearly 8.5 ft, which makes it the largest arthropod ever.
- Sarcosuchus, a distant relative of living crocodiles, lived about 112 million years ago. It had somewhat telescoped eyes and a long snout with 35 teeth on each side of its upper jaw and 31 teeth on each side of its lower one.
- Gorgonopses lived around 260 million years ago, terrifying all the smaller species of that time. As for their size, these creatures were about 10 ft long and weighed nearly 1,000 lb. They were basically at the top of the food chain.
- Titanoboa lived in the region that's now a part of northeastern Colombia, and its fossils date back to about 58–60 million years ago. Titanoboa holds the scary record for the largest snake ever discovered with a total length of nearly 48 ft and a weight of about 2,500 lb.
- Meganeuropsis still continue to be the biggest insect of all time with a wing length of 13” and a body length of almost 17”. The very first fossils of Meganeuropsis were actually discovered in France back in 1880.
- Helicoprion lived was around 290 million years ago, living in North America, Eastern Europe, Asia, and Australia's waters. The most distinctive feature of Helicoprion was its circular jaw. Helicoprions proved to be incredibly strong since they survived the Permian-Triassic Extinction Event that killed 90% of marine animals and around 70% of terrestrial ones.
