Sclerites

Halkieriids are Cambrian animals that looked like slugs in scale mail; often when they died their scales, called sclerites, dissociated and scattered, and their sclerites represent a significant component of the small shelly fauna of the early Cambrian. ❋ Unknown (2007)

[3] The exoskeleton is made up of many plates which are called sclerites, and are separated by thin sutures. ❋ Unknown (2009)

Like the halkieriids, it has an anterior shell but not a posterior one, and like the wiwaxiids, it has long spiky sclerites. ❋ Unknown (2007)

Wiwaxiids were also sluglike, but sported very prominent, long sclerites, and lacked the anterior and posterior shells; their exact position in the evolutionary tree has bounced about quite a bit, but some argument has made that they belong in the annelid ancestry, and that their sclerites are homologous to the bristly setae of worms. ❋ Unknown (2007)

Edit do the sclerites resemble the modern calcareous plates of chitons? kay ❋ Unknown (2007)

Like Vetustovermis, Kimberella has many structures crenellations that may have been gills, has a broad flat foot, showing metamerism, and its shell bears many impressions, which may be the remains of sclerites or spicules. ❋ Unknown (2005)

Cervical sclerites: small ebitinous plates on the membrane between head and thorax: see jugular sclerites. ❋ John. B. Smith (N/A)

Patagium - ia: in Lepidoptera, those sclerites that cover the base of primaries: often used as synonymous with tegula and squamula, q.v.: assigned by some writers to the pro -, by others to the meso-thorax: homologized with the paraptera of meso-thorax. ❋ John. B. Smith (N/A)

Entothorax: applied to the apodemes or processes extending inwardly from the sternal sclerites: see apophysis. ❋ John. B. Smith (N/A)

Parapteron - era: small sclerites, articulated to the dorsal extremity of the episternum, just below the wings; absent on prothorax = the tegulae of Hymenoptera, and patagia of Lepidoptera: have been homologized with the elytra of Coleoptera. ❋ John. B. Smith (N/A)

Axillae: two small, subtriangular sclerites at the lateral basal angles of the meso-scutellum in Proctytripidae. ❋ John. B. Smith (N/A)

Epimera - eron: the posterior lateral thoracic sclerites; usually small, narrow or triangular. ❋ John. B. Smith (N/A)

Hypopharyngeal sclerites: in bees, a pair of strap-like pieces along the hypopharynx to the mentum: see also epipharyngeal sclerites. ❋ John. B. Smith (N/A)

Apophystegal plates: Orthoptera; flattened blade or plate-like sclerites covering the gonapophyses. ❋ John. B. Smith (N/A)

Parapsidae: the small sclerites on each side of the scutellum in ❋ John. B. Smith (N/A)

Epipharyngeal sclerites: in bees; a pair of strap-like pieces extending backward from the two sides of the base of epipharynx: see hypopharyngeal sclerites. ❋ John. B. Smith (N/A)

Conjunctiva: the membrane uniting the abdominal sclerites. ❋ John. B. Smith (N/A)
