The Godzilla Shark is a unique and fascinating creature. At 6.7 feet long, this shark was one of the largest of its kind during its lifetime. By comparison, many modern sharks are much bigger. Yet this ancient shark was massive for its time.
The Hoffman's Dragon Shark (Dracopristis hoffmanorum) is an extinct species of shark that lived during the Carboniferous period about 307 million years ago. The fossil of this prehistoric shark was discovered in New Mexico in 2013, and the first full description was published in 2021.
We know that megalodon had become extinct by the end of the Pliocene (2.6 million years ago), when the planet entered a phase of global cooling. Precisely when the last megalodon died is not known, but new evidence suggests that it was at least 3.6 million years ago.
First, the climate dramatically changed. Global water temperature dropped; that reduced the area where megalodon, a warm-water shark, could thrive. Second, because of the changing climate, entire species that megalodon preyed upon vanished forever.

In the original Japanese films, Godzilla and all the other monsters are referred to with gender-neutral pronouns equivalent to "it", while in the English dubbed versions, Godzilla is explicitly described as a male. In his book, Godzilla co-creator Tomoyuki Tanaka suggested that the monster was probably male.
King Ghidorah showed that Godzilla mutated from a late-surviving theropod dinosaur. The carnivore looked like the old, dumpy restorations of Tyrannosaurus from the mid-20th century, and, no surprise, the fictional dinosaur is known as Godzillasaurus.
Ghost sharks are not actual sharks, but a species of fish closely related to sharks and rays. They are cartilaginous - meaning their skeletons are primarily composed of cartilage - which gives them an eerie, ethereal quality.
While zebra sharks are a species that can reproduce asexually, it is rare. Researchers said it's even more unusual that Bubbles chose parthenogenesis even though she was exposed to three mature breeding males. "Now the question becomes why," said Kevin Feldheim, Field Museum lab manager.
