An old judicial worm with sharp teeth rings was discovered in Grand Canyon

About 500 million Years ago, Grand Canyon was a wonderful sea, and was among the creatures sheltering a kind of newly discovered penis, armed with many toothpicks.

Penis worms are marine creatures with a clear appearance. There are more than 20 known species who live throughout the world today, as well as a number of those extinct, such a new discovery. The researcher who searched for fossils in Grand Canyon was called the species Kraytdraaco spectaus In honor of the huge Krayt Dragons deception that appears in the world of stars. Details of the discovery were published in the magazine Science progress.

The authors believe that the worm is nourished with a retreating throat that can be pushed out, from the inside out, before it is drawn on itself – like the inverted glove finger. The lining of this throat was rings and dental rings.

In an attempt to imagine how the old worm may nourish it, researchers assume that along this Proboscis, combining strong and sharp teeth with the most sensitive feather of the eating process in two phases. The first could have been used to capture food such as algae and microorganisms that were dispersed in the sand where the worm would live, and the other to filter this food from the substrate and chew. But after there were fossils to look at it, and the inability to see the worm at work, this remains just a hypothesis.

The adult sample could have a length of about 15 to 20 cm. This is much larger than the types of penis worm that lives today, which has undergone miniaturization over thousands of years and now does not exceed 2 to 3 millimeters.

Despite the attention of steam scientists in the teeth, the excavations of other creatures were found in the same campaign. It has been estimated so far by the beginning of the Cambrian period, about 500 million years ago, which experts consider the dawn of complex animal life. These other creatures, early species of shrimp and mollusks, are valuable because they indicate the shape of the first predators in the world.
