However, there are major biological differences between brachiopods and bivalves. A mirror image or plane of symmetry of a brachiopod cuts the valve in half along its length (Figure 9). In bivalves the mirror image runs along the edge of the Spirifer is a genus of marine brachiopods belonging to the order Spiriferida and family Spiriferidae. Species belonging to the genus lived from the Middle Ordovician ( Sandbian) through to the Late Triassic ( Carnian) with a global distribution. They were stationary epifaunal suspension feeders.

Bryozoa are a group of aquatic (marine and freshwater) invertebrates that are colonial, meaning many individuals live together. These colonies can be in a variety of shapes that include massive (solid), foliaceous (sheet-like), dendroid (branching), or fenestrate (windowed-shape) ( UCMP ). Bryozoa are first recorded in the Early ... Brachiopods are triblastic organisms. This means that during their embryonic development they present the three germ layers: ectoderm, mesoderm and endoderm. From these, the various organs that will make up the adult individual are generated. Similarly, they have coelom, a cavity that is formed from the mesoderm.Fossils to ID 2016 - Set A.doc 1 of 23 11/22/2015 10:03:00 PM Phylum: Foraminifera Common Name: Forams or “hole bearers” (Latin) Habitat: Most marine plankton, some freshwater, some benthic.

Size. varies from 5mm to 8cm, some up to 38.5cm. feeding. To feed the brachiopod has to open its valves to let in fresh water. Valves are opened by the contraction of the didductor muscles. Mollusca is the second-largest phylum of invertebrate animals, after Arthropoda; members are known as molluscs or mollusks [a] ( / ˈmɒləsk / ). Around 76,000 existent species of molluscs are recognized. [3] The number of fossil species is estimated between 60,000 and 100,000 additional species. [4] The proportion of undescribed species is ...Although lophophore morphology differs substantially among brachiopods, the tentacles are organized similarly among the different species. In most brachiopods, there is an outer and an inner row of tentacles. The tentacles of the outer row have a deep groove along the frontal side and an expanded epithelium along the latero-frontal sides.…

Both valves may be convex (biconvex) and the ... These brachiopods have been transported from th Brachiopod shells come in a variety of shapes and sizes. Sometimes the bottom valve is convex like the top valve, but in many species the bottom valve is concave or occasionally conical. In some brachiopods, the top valve is concave and the bottom is convex. The outer surface of the valves may be marked by concentric wrinkles or radial ribs.Bryozoans are filter feeding invertebrates and can be found in both freshwater and marine habitats, where they are often easy to miss because of their small size and cryptic lifestyle (e.g., encrusting seashells, rocks, or kelp).
