The spelling of the word "entrochites" can be explained using IPA phonetic transcription as [ˈɛntrəkaɪts]. Breaking it down, the first syllable, "en," is pronounced like "en" in "end". The second syllable, "tro," is pronounced like "tro" in "trophy". The third syllable, "chi," is pronounced like "ki" in "kitten". The fourth syllable, "tes," is pronounced like "tess" in "test". Therefore, the correct way to spell "entrochites" is with an "e," an "n," a "t," an "r," an "o," a "c," an "h," an "i," a "t," and an "es".
Entrochites is a term used in the field of paleontology to refer to a genus of extinct marine invertebrates belonging to the family of crinoids. Crinoids, commonly known as sea lilies or feather stars, are echinoderms that lived predominantly in the Paleozoic era, between the Ordovician and Permian periods.
Entrochites are characterized by their cup-shaped or barrel-shaped calyx, which is the hard, protective structure housing their internal organs. The calyx of entrochites is composed of numerous calcite plates, known as ossicles, which are arranged in a symmetrical pattern. These ossicles often contain intricate designs and ridges, and they are often fossilized and preserved in sedimentary rocks.
The entrochite's calyx is attached to a stem composed of a series of stacked sections, called columnals, which allowed it to anchor itself to the ocean floor. The stem of entrochites is flexible and made of a combination of organic matter and calcite, although the organic material is rarely preserved in the fossil record.
As filter feeders, entrochites had a specialized feeding apparatus called a pinnulate arm. These arms were lined with feather-like structures known as pinnules, which captured plankton and other tiny organisms from the surrounding water.
Fossils of entrochites are found in various parts of the world, and their study provides valuable insights into the ancient marine ecosystems and the evolution of life on Earth during the Paleozoic era.
Name given to the wheel-like joints of the encrinite, also called entrochi and trochitae.

The word "entrochites" has its origins in the combination of two Greek words: "entos" meaning "within" or "inside", and "trochus" meaning "wheel" or "circular movement".
In ancient Greece, "trochus" referred to a pulley or a turning wheel. It was later used in biology to describe disc-shaped fossils, which were thought to resemble pulleys.
During the 19th century, the term "entrochites" was coined to specifically refer to fossilized circular or disc-shaped structures found in rocks. These structures resembled wheels or rotors, hence the adoption of "trochus" in the word.
Over time, the definition of "entrochites" has evolved. Today, it generally refers to fossilized remains of crinoids, a type of marine echinoderm, often characterized by their circular or disc-shaped structures.
