Spinosaurus is currently the largest of all known carnivorous dinosaurs, even larger than T. rex and Giganotosaurus.
The creatures that resided on planet earth before us were quite terrifying and lethal. Most of them went extinct over the years as they could not survive once the atmospheric conditions of our planet changed. Scientists, however, have discovered numerous fossils that tell us a haunting yet intriguing tale. Imagine swimming in an ocean with megalodon or basilosaurus. None of us would have survived as the animals I am referring to were simply deadly. Most of them were quite massive and used to eat other creatures to fill their bellies. All in all, it is difficult to cage or curb predators, so I’m glad we no longer have any ancient animals living on planet earth.
Following are ten intriguing predators that once roamed freely on planet earth. Let’s have a look at them, shall we?
1) Megalodons were approximately 59-feet long sharks:
The Megalodon shark was at least 59-feet long. It lived and hunted in the same waters as Livyatan Melvillei. As per various studies, it had over five rows of 276 sharp, blade-like teeth that were made for shredding and grasping mighty prey.
Experts could not find megalodon’s fossils as sharks have skeletons that are made up of cartilage. Hence, they cannot be preserved. Scientists were able to find teeth of the megalodon sharks that shed some light on the creature’s size. The megalodon sharks were the ancestors of the white sharks; they had similar bodies but were larger and heavier than them. Sharks are known for shaking their prey side to side to enhance bite forces. Fossil evidence of teeth marks found on whale vertebrae infers that megalodon was an active predator of whales.
2) Basilosaurus whales could walk on the surface:
Basilosaurus could walk on the surface. They were initially classified as reptiles but were later described as whales that could walk. They roamed freely on earth back in the olden days. However, they eventually evolved into species that could only survive underwater. Whales permanently moved to the ocean about 50 million years ago. Furthermore, multiple studies suggest that Basilosaurus were approximately 60-foot long. They had a mighty bite that was quite similar to that of Tyrannosaurus. Multiple teeth marks were discovered on the fossils that suggested the existence of Basilosaurus whales.
3) Jaekelopterus were massive sea scorpions that used to tear other creatures in a single go:
Jaekelopterus were giant sea scorpions that were almost 8-foot long. They thrived underwater and had pincher claws. Moreover, these giant scorpions had segmented bodies with various specialized limbs, specifically designed to break and abolish the prey. Jaekelopterus have become extinct over years. Multiple smaller sea scorpions still crawl to the surface to shed their external skin; envision locating a moult of one of these monsters on the shore just before going swimming. I assure you, it won’t be a pleasant sight.
4) The Giganotosaurus were bigger than the Tyrannosaurus rex:
The Giganotosaurus were approximately 43 feet long and were larger than the Tyrannosaurus. According to various scientists, they had a 5.2-foot long skull with over 64 inch-long packed teeth that were specifically designed for tearing flesh. Giganotosaurus thrived during the Cretaceous period and lived in what is now Argentina. Experts have accumulated sufficient data that suggests that the Giganotosaurus hunted giant sauropods. Moreover, their lower jaw was slightly larger to grip and tear smaller prey.
5) Meganeuropsis are known as the largest dragonflies:
The Meganeuropsis’ wingspan was about 28 inches. They resided on planet earth approximately 300 million years ago. Also, they looked like massive dragonflies but were quite lethal in real. Scientists are still questioning why Meganeuropsis evolved to be so large. One of the studies suggests that oxygen levels were higher during the Permian era. Hence, most of the insects grew massive during that period.
7) Titanoboa thrived in the Paleocene period and gave its prey a crushing and brutal death:
The Titanoboa was a 42-foot long snake that existed during the Paleocene period. As per various experts, its ideal diet was crocodiles and other massive sea creatures. It prowled near the edge of the water so it could attack thirsty, unsuspecting animals. It would hit from the water and coil itself around its prey, giving a crushing and brutal death. It existed in the rain forests of South America, where the atmosphere was warmer than the tropics of today. This is why the cold-blooded reptiles grew larger than the modern creatures.
8) The Tully monsters were basically ‘jawless fish’:
Illinois was a tropical sea back in the olden days, and the Mazon Creek area outside of Chicago is a motherlode of soft-bodied animals fossils. Scientists were able to discover the fossils of the Tully monsters in that particular region. The Tully monsters have eyes on stalks and a jaw connected with a noodly proboscis. The experts at Field Museum ultimately concluded that the Tully monsters are jawless fish, distant relatives of the lampreys that are still alive in this age and day.
9) Sarcosuchus consumed dinosaurs and other massive creatures of the Cretaceous period:
Sarcosuchus was a 40-foot long reptile that resembled a crocodile. It existed during the Cretaceous era. The best part about this creature is that it could live in all sorts of atmospheric conditions. It had a 6-foot long skull that contained over 132 sharp teeth. Moreover, Sarcosuchus was larger than most of the dinosaurs that lived during that era. This particular monster ate dinosaurs and other massive creatures.
10) Spinosaurus is currently the largest of all known carnivorous dinosaurs:
Spinosaurus is considered as one of the most horrible and lethal creatures that walked the Earth. It had a massive, elongated skull that resembled a crocodile. Moreover, its snout was filled with over 64 pointed teeth. Multiple studies suggest that it was semi-aquatic, so it devoured all sorts of creatures. Spinosaurus is currently the largest of all known carnivorous dinosaurs, even larger than T. rex and Giganotosaurus.
