Biophysical Controls on Sediment Suspension in South Bay, VA 2013-2014
Research was conducted in South Bay, Virginia, a shallow (1-2 m mean depth) subtidal coastal bay on the Delmarva Peninsula. Hydrodynamic measurements including current velocity, wave characteristics, shear stress, as well as biological samples, light and SSC data were recorded for 1-3 weeks over 2 consecutive years during the spring, summer, fall and winter seasons. See: Ross Timmerman 2014. Biophysical Controls on Sediment Suspension in a Shallow Coastal Bay. M.S. Thesis, University of Virginia. Data tables are included for sediment characteristics, wave height, wave vector measurements and light.
Data from: The Collins' monster, a spinous suspension-feeding lobopodian from the Cambrian Burgess Shale of British Columbia
Lobopodians, a paraphyletic group of Palaeozoic vermiform animals bearing metameric appendages, are key to the origin of extant panarthropods. First discovered in 1983 on Mount Stephen (Yoho National Park, British Columbia), the Cambrian (Wuliuan) Burgess Shale lobopodian nicknamed "Collins' monster" is formally described as <i>Collinsovermis monstruosus</i> gen. et sp. nov. A formal systematic revision of the poorly known lobopodian <i>Acinocricus stichus</i> from Utah is also provided. The body of <i>Collinsovermis</i> is plump and compact, lacking space between lobopod pairs but shows the diagnostic suspension-feeding characters of luolishaniid lobopodians. The six anterior lobopod pairs are elongate, adorned with long and slightly curved ventral spinules arranged in a chevron-like pattern. The eight posterior lobopod pairs, which attach to a truncated body termination, are stout and smooth, each terminated by a single strong recurved claw. Each somite bears a pair of dorsal spines; somites 4 and posteriad bear an additional median spine. The spines on somites 1–3 are much shorter than the spines on the remaining somites. The head is short, bears a pair of antenniform outgrowths, and is covered by an oblong sclerite. <i>Collinsovermis</i> plus <i>Collinsium</i> and <i>Acinocricus</i> comprise a sub-group of stout luolishaniid lobopodians with remarkably long spinules on the front lobopods, interpreted here as a clade (Teratopodidae). This clade is distinct from both the comparatively slenderer <i>Luolishania</i> and a sub-group composed of <i>Facivermis</i> and <i>Ovatiovermis</i> with posterior lobopods reduced or absent. Luolishaniids were mostly sessile forerunners of arthropods that had coupled efficient suspension-feeding devices and, as in <i>Collinsovermis</i> defensive features.

Wmid-27bdd3 - Medieval suspension weight
A complete lead or lead alloy weight of the Medieval to Post-Medieval period, dating from c. AD 1200 to AD 1800. The weight consists of a globular oval shape, with an integral sub triangular suspension loop at the top of the weight. The loop has a lozenge (diamond shaped) in section. A vertical ridge is present around the midline, probably a remnant from a two piece mould used in the casting process. One side of the weight has a recessed centre with a raised long cross on it, positioned centrally. The other side has a deep groove running vertically.

Reconstructing the feeding ecology of Cambrian sponge reefs: The case for active suspension feeding in Archaeocyatha
Sponge-grade Archaeocyatha were early Cambrian biomineralizing metazoans that constructed reefs globally. Despite decades of research, many facets of archaeocyath palaeobiology remain unclear, making it difficult to reconstruct the palaeoecology of Cambrian reef ecosystems. Of specific interest is how these organisms fed; previous experimental studies have suggested that archaeocyaths functioned as passive suspension feeders relying on ambient currents to transport nutrient-rich water into their central cavities. Here, we test this hypothesis using computational fluid dynamics (CFD) simulations of digital models of select archaeocyath species. Our results demonstrate that, given a range of plausible current velocities, there was very little fluid circulation through the skeleton, suggesting obligate passive suspension feeding was unlikely. Comparing our simulation data with exhalent velocities collected from extant sponges, we infer an active suspension feeding lifestyle for archaeocyaths. The combination of active suspension feeding and biomineralization in Archaeocyatha may have facilitated the creation of modern metazoan reef ecosystems.

A Permian fish reveals widespread distribution of neopterygian-like jaw suspension
<p>The actinopterygian crown group (comprising all living ray-finned fishes) originated by the end of the Carboniferous. However, most late Paleozoic taxa are stem actinopterygians, and broadly resemble stratigraphically older taxa. The early Permian †<em>Brachydegma</em> <em>caelatum</em> is notable for its three-dimensional preservation and past phylogenetic interpretations as a nested member of the neopterygian crown. Here, we use computed microtomography to redescribe †<em>Brachydegma</em>, uncovering an unanticipated combination of primitive (e.g., aortic canal; immobile maxilla) and derived (e.g., differentiated occipital ossifications; posterior stem of parasphenoid; two accessory hyoidean ossifications; double jaw joint) endoskeletal features relative to most other Paleozoic actinopterygians. Some of these features were previously thought restricted to the neopterygian crown. The precise phylogenetic position of †<em>Brachydegma</em> is unclear, with placements either on the polypterid stem, or as an early-diverging stem neopterygian. However, our analyses decisively reject previous placements of †<em>Brachydegma</em> in the neopterygian crown. Critically, we demonstrate that key-endoskeletal components of the hyoid portion of the suspensorium of crown neopterygians appeared deeper in the tree than previously thought.</p>
