Flickr photos, groups, and tags related to the "spiriferida" Flickr tag.Spiriferida-brachiopod. Spiriferid are brachiopods filtering feeders that fed on organic particles washed around by the ocean currents. The valves (each shell side) has pronounced folds and sulcus (furrow, fissures). They lived in mud by anchoring to the sea floor with a fleshy stalk called a pedicle that protruded from the shell’s hinge. Ang Zygospira modesta, mga spiriferid brachiopod naingatan sa kanilang mga orihinal na posisyon sa isang trepostome bryozoan; Cincinnasiyano(Itaas na Ordovician) ng katimugang silangang Indiana. The earliest horseshoe crab fossils are found in strata from the late Ordovician period, roughly 450 million years ago.

Jul 7, 2009 · Articulate brachiopods are known to depend on ambient fluids for their feeding and respiration under certain circumstances (e.g., Rudwick, 1970; James et al., 1992; LaBarbera, 1977, LaBarbera, 1981, LaBarbera, 1984).

Open-ended tubes were found extending inward from the inner surfaces of brachial valves of three different species of Emsian spiriferid brachiopods. It is believed that these tubes were formed by the outer epithelium of the brachiopods, precipitating shell material around a small commensal filter feeding organism living in the outer mantle cavity. Order Productida. The Productids were an extremely successful and diverse group of brachiopods, dominating late Paleozoic marine ecosystems. Productids are characterized by concavo-convex shells accompanied by development of spines, either along the posterior margin, or distributed more or less abundantly over other parts of the shell surface ...Dec 3, 2018 · The only info I have on this little spiriferid brachiopod is that it’s from Canada.

The most remarkable feature of this brachiopod assemblage, besides the very good preservation, is the very low taxonomic evenness and diversity. This impoverished, low diversity/high density ...

This is a very large spiriferid brachiopod fossil. It looks like a large, more robust, version of M. audaculus. It is very rounded, and the hinge line is not straight, but is slightly concave. It's called spinocyrtia because of fine spines (almost like tiny hairs) that cover the brachiopod. These spines are only preserved on exceptional specimens.
