 | | However, it is less clear what to do when the simple removal of one or a few unrelated taxa from a formerly polyphyletic taxon, leaving the concept more or less intact, and leaving a monophyletic taxon as well. | | | Such is the case with the name Trilobitomorpha (also see below) for example. | | | There are also those who argue that taxonomic names should not be allocated to paraphyletic groups - which would potentially rule out such useful terms as "fish", "reptile" and probably "sponge" as well, if carried to its ridiculous extreme. |

| | The Trilobitomorpha is a subphylum of the phylum Arthropoda that includes the trilobites. | | | However, the many speciesâ”known only from fossilsâ”do not appear to be closely related to the trilobites or, in many cases, to each other either, and are now generally placed in separate subphyla when classified at all. | | | Subphyla and Classes Subphylum Trilobitomorpha Trilobita - Trilobites (extinct) Subphylum Chelicerata Arachnida - Spiders, Scorpions, etc.... |

| | A CLADISTIC ANALYSIS OF TRILOBITOMORPHA TO CHELICERATA AND CRUSTACEA |
| | The Trilobites, the Crustaceans, and the Chelicerates are all grouped in the phylum Arthropoda, which are believed to have evolved from annelid ancestors. | | | The Chelicerata, Crustacea, and Trilobitomorpha were analyzed cladistically in order to determine whether the Trilobites are more closely related to the Chelicerates or to the Crustaceans. | | | The results observed from the phylogram show that the Trilobitomorpha are more closely related to the Crustacea than the Chelicerata, which supports Margulis and Schwartz’s (1998) classification. |

| | "Trilobitomorpha with eurypterid or xiphosurid type of body, trilobation more or less distinct; tergites of trunk free or ankylosed into continuous shield, telson mostly styliform; 1st and last pair of trilobite appendages may be modified and others partly reduced" | | | The Artiopoda include many of the "Trilobitomorpha" (primitive trilobite-like forms) | | | Included around the base of the "Crown Group" Chelicerata are a number of primitive forms called "Merostomoidea" - which seem to be transitional between Trilobites and Chelicerates proper. |

| | Trilobite |
| | The segmented body primitively bears a pair of jointed appendages on each segment. | | | A recent interpretation of arthropod phylogeny abandons the name Trilobitomorpha and places trilobites in the taxon Trilobita | | | Arthropoda, by far the largest and most diverse animal taxon, includes chelicerates, insects, myriapods, and crustaceans as well as many extinct taxa such as Trilobitomorpha. |

| | Order Nectaspida |
| | The name Trilobitomorpha is not much used today, although a case could be made that it is available for naming the informal "trilobite clade" concept. | | | Størmer (1944) proposed the name Trilobitomorpha to include the Trilobita and a miscellaneous collection of other Burgess Shale arthropods which he later (Størmer 1959) named the Trilobitoidea. | | | Description: Small arthropods with cephalic and abdominal shield; subelliptical, trilobate body; cephalon with small sessile eyes; post-abdomen short and narrow with ?single segment and short lanceolate telson bearing lateral spines; first antennae short with numerous setiferous joints; other appendages probably trilobitic. |

| | Superclass Trilobitomorpha |
| | Therefore, the only widely accepted class is the Trilobita, whose character states are nearly identical with those of Superclass Trilobitomorpha. | | | Superclass Trilobitomorpha is broken into two classes: Trilobita and Trilobitoidea; the latter of which warrants discussion due to its uncertainty. | | | The present tool for trilobite classification is hypostome location and character (Fortey, 1990). |

| | The phylum Arthropoda (Greek for "jointed legs") comprises four major groups: Uniramia (insects and their allies), Chelicerata (such as spiders and scorpions), Crustacea (the often-eaten lobsters and shrimps are in this group) and the extinct Trilobitomorpha (trilobites). | | | Insects are by far the most successful animal group on the planet. |

| | Members of the class Arachnida were some of the very early terrestrial inhabitants. | | | Members of the subphylum Trilobitomorpha were a dominant form of life in the ocean during the Cambrian period (600 million years ago) to the Carboniferous period (345 million years ago). | | | Today, a few living species of trilobites inhabit deep water along the eastern coast of North America. |
