“Godzilla Shark”, The Newly Found Sea Monster Fossil

           A 300-million-year-old shark has been found by John Paul Hodnett, paleontologist from Northern Arizona University and the New Mexico Museum of Natural History and Science.

          The sea monster that was a kind of ancient shark was found in the Monzano Mountains, east of Albuquerque, New Mexico. Hodnett first came across the tip of the shark’s nose that was embedded in a rock before he digs it up.

          Hodnett explained: "We are calling it Godzilla shark because of their similar physical characteristics.”

          According to him, the similar characteristics that resemble Godzilla are the short and sharp teeth, the disproportionately large dorsal fin, body skin that similar to a reptile, and its huge size.

          Analysis with CT scan showed that this Godzilla shark has an unusual face; it has teeth on its lips. This species still has teeth on the mouth but it has extra teeth on the outside.

          “So having teeth on the outside of the lip may help them in grasping and securing prey in the mouth before they kill it. To put it simply, the extra teeth on the outside of the mouth gave Godzilla shark a better bite with the jaws it had,” he added.

How Sinkholes Occurs

          Sinkholes are depressions in the ground that form because of erosion and gravity. A sinkhole usually forms by erosion caused by frequent exposure to water. It is caused by pressure on the soil surface of the ground that occurs when an underground layer is unable to sustain the structure of the layer above it. Most sinkholes occur in areas where the bedrock is formed from soft minerals and rocks like salt, gypsum, limestone, dolomite or other evaporate classes of rocks.

          The flowing acidic water dissolves rock and carves out conduits, or underground passages, through which more water will eventually flow. These conduits in turn help to develop underground basins known as recharge areas. These underground pools of water constantly have water flowing to and from them, which further erodes the bedrock. Eventually, the bedrock will be so eroded that it can no longer support the weight of the topsoil above it. When this happens, the topsoil - also called overburden - caves in, creating the sinkhole.

          This is how a sinkhole is occurred.
