1. An awful-looking dinosaur shark
Similar to Helicoprion, Edestus is another extinct creature whose precise shape still begs to be disproven. Edestus also didn’t lose teeth the way Helicoprion did. The newly formed teeth and gums that had just emerged close to the back of the mouth pushed the more mature teeth and gums forward and created some sort of tooth-tastic oral display.
A logical article from around 1900 suggests that Edestus may have looked like this.
2. A 50-foot-long terrifying monster with a destructive nature
After the dinosaurs were wiped off a long time ago, the Titanoboa replaced them as the largest and riskiest hunter on Earth. They had a length of 50 feet, weighed 2,500 pounds, and killed their prey by narrowing.
3. A massive aquatic scorpion
Think of a scorpion that uses its oar-like body as a swimming tool. Consider it to be 5 feet long at this point. The Pentecopterus decorahensis, which was most recently seen in 2015, was swimming close to what is now Iowa at some point in the distant past.
The extinct organism has living cousins in ticks, insects, and lobsters.
4. A sauntering worm
A worm with legs for propulsion. which may be considered appendages. They might have had mouths at the closures, but they probably didn’t.
The reason this species is known as Hallucigenia fortis is made more widely known by it. Hallucigenia was thankfully only a little over two inches long.
5. A fish with teeth capable of severing bone
The Dunkleosteus formerly held control of the earth. It was a fish that grew to be more than 30 feet long and was unmistakably covered in defense. Due to its nose-like mouth, which was designed specifically for biting through protection like its own, it might have been a barbarian animal category or an animal group that took part in local conflict.
Their jaws were so powerful that they could twist them to quickly open and close them.
