The Project involves the training and mobilization of a large corps of volunteers and is currently the only program with the technical and organizational ability to gather marine biodiversity data in a systematic and reliable manner. Objectives of the project are: 1.) to provide training and education opportunities for SCUBA divers and snorkelers to learn to identify and appreciate marine life 2.) to make data and summary reports readily accessible to the marine science, resource management, and conservation communities …
Microstratigraphic Analysis Of Burrow-Reworked Dinosaur Track Bed At Joanna's Track Site, Cretaceous Glen Rose Formation, Glen Rose, Texas, Michael Blair, Benjamin Dattilo, Anthony Martin, James Farlow
Microstratigraphic Analysis Of Burrow-Reworked Dinosaur Track Bed At Joanna's Track Site, Cretaceous Glen Rose Formation, Glen Rose, Texas, Michael Blair, Benjamin Dattilo, Anthony Martin, James Farlow
Benjamin F. Dattilo
Although dinosaur trackways are common in the Cretaceous Glen Rose Formation of Texas, the recently discovered Joanna track site illustrates a unique ichnological relationship where dinosaur tracks were disrupted by invertebrate burrows made long after burial. In an effort to document the precise sequence of events, we described the interval from 0.3 m below the track layer through 2.7 m above it in a vertical outcrop adjacent to the track site, focusing on the 70-cm of strata immediately above the track horizon. An 8-meter N-S cross-section of this 70-cm interval was power-washed, examined for trace fossils, body fossils, and lithology …

Push Me – Pull You: Experimental Biomechanics Of Immobile Suspension Feeders On Soft Substrates, Roy Plotnick, Benjamin Dattilo, Joshua Corrie, Daniel Piquard, Jennifer Bauer
Benjamin F. Dattilo
Immobile suspension feeders on soft substrates (ISOSS; Thayer 1979) although rare in modern marine habitats, were relatively common in the Paleozoic. Numerous Paleozoic taxa have been interpreted as dwelling on soft unconsolidated sediments and possessing morphologic features that either anchor them to the sea floor (e.g., crinoid holdfasts) or prevent them from sinking in (strophomenid brachiopods). Thayer (1975) reviewed the morphologic adaptations for forms living on soft-muddy bottoms and provided a quantitative expression of the static stresses involved. The same quantitative expression can also be used to describe the forces involved in anchoring. With the exception of Leighton and Savarese …
An Unusual Association Of Pseudolingula And Rafinesquina From The Upper Ordovician Of Ohio, Benjamin Dattilo, Rebecca Freeman, Bryan Utesch, Steve Felton, John Pojeta
An Unusual Association Of Pseudolingula And Rafinesquina From The Upper Ordovician Of Ohio, Benjamin Dattilo, Rebecca Freeman, Bryan Utesch, Steve Felton, John Pojeta
Benjamin F. Dattilo
Late Ordovician members of Order Lingulida, for the most part, resemble modern lingulids in their infaunal habits and marginal habitats. Pseudolingula, a common Cincinnatian form, is often found preserved in burrows in life position, and as such, it could probably escape moderate sediment accumulations. An unusual association of thousands of specimens of the lingulate Pseudolingula and hundreds of the strophomenid Rafinesquina in the Upper Ordovician of the Cincinnati, Ohio region presents an interesting case. This association occurs on 4-square-meter exposure of a 10 cm shell bed in the Fairview Formation at Harsha Lake, Ohio. The bed is covered with Rafinesquina …

The Curse Of Rafinesquina: Negative Taphonomic Feedback Exerted By Strophomenid Shells On Storm-Buried Lingulids In The Cincinnatian (Katian, Ordovician) Series Of Ohio, Rebecca Freeman, Benjamin Dattilo, Aaron Morse, Michael Blair, Steve Felton, John Pojeta
Benjamin F. Dattilo
Thousands of lingulid brachiopods were found clustered beneath hundreds of individual valves of the strophomenid brachiopod Rafinesquina in the Upper Ordovician of Ohio. This association suggested a relationship between the two brachiopods, but the nature of this relationship was unclear. We utilized serial thin sectioning to examine these brachiopods and to determine the origin of the bed in which they were found. Sedimentary structures, mixed taphonomies, and stratigraphic and paleogeographic setting suggest that the lingulids occupied a hiatal concentration that had previously been reworked, but not significantly transported, by tropical storms. The final burial event was a storm that exhumed …
The “Passive Implanter” Strategy Of The Adult Ordovician Brachiopod, Platystrophia Ponderosa., Sadye Howald, Benjamin Dattilo
The “Passive Implanter” Strategy Of The Adult Ordovician Brachiopod, Platystrophia Ponderosa., Sadye Howald, Benjamin Dattilo
Benjamin F. Dattilo
Platystrophia ponderosa is found throughout the Maysvillian Strata of the Cincinnati Ordovician. This species thrived in a high energy environment with only muddy shell gravels, and no solid substrates for pedicle attachment. Our growth-series studies show juveniles of this species had large pedicle openings, thin shell, small size, nearly flat shape, and shallow sinus/sulcus. In contrast, the adults had relatively small pedicle openings obstructed by a large beak, secondary thickening of the pedicle valve making it considerably thicker than the brachial valve, large size (up to 4cm in diameter), spherical shape, and deep sinus/sulcus. The morphological characteristics of the adult …
How Many Track Horizons Are Exposed At Dinosaur Valley State Park? Stratigraphy Of The Cretaceous Glen Rose Formation Track Sites Of The Paluxy River, Glen Rose, Texas, Benjamin Dattilo, Sadye Howald, James Farlow, Anthony Martin
How Many Track Horizons Are Exposed At Dinosaur Valley State Park? Stratigraphy Of The Cretaceous Glen Rose Formation Track Sites Of The Paluxy River, Glen Rose, Texas, Benjamin Dattilo, Sadye Howald, James Farlow, Anthony Martin
Benjamin F. Dattilo
The dinosaur tracks of the Glen Rose Formation in the Paluxy River at Dinosaur Valley State Park are among the best preserved and most abundant in the world. While many track sites are easily correlated to the Main Tracksite, others, especially those at the extreme ends of the park, are differently preserved and not obviously correlated. To count track horizons, several stratigraphic sections were measured along the river from upstream at the McFall Ledge Site to 7.6 km downstream at the County Road 1001 crossing (3.1 km linear distance). These reveal 6 meters of strata separating two track-bearing horizons exposed …
Stop Clinging! –How The Ordovician Brachiopod (Fka Platystrophia) Vinlandostrophia Ponderosa Outgrew Its Mid-Life Attachment Crisis, Benjamin Dattilo, Sadye Howald
Stop Clinging! –How The Ordovician Brachiopod (Fka Platystrophia) Vinlandostrophia Ponderosa Outgrew Its Mid-Life Attachment Crisis, Benjamin Dattilo, Sadye Howald
Benjamin F. Dattilo
The high-energy nearshore environment and muddy shifting shell gravels recorded in Maysvillian strata of the Cincinnati Ordovician might seem particularly inhospitable to brachiopods, which generally require solid surfaces for attachment. Nevertheless, Vinlandostrophia ponderosa thrived and even characterizes these facies. A preliminary study of growth series suggests that, like the full-grown stages of related species, smaller V. ponderosa were attached by pedicle. Smaller specimens have a large pedicle opening, a nearly flat shape, thin shell, and a shallow sinus/sulcus, leaving the commissure nearly flat. These characteristics are consistent with strong, erect pedicle attachment, even stronger than found in related species, whose …

Gape, Feeding Currents And Valve Snapping In Thecidellina Meyeri From Curaçao, Netherlands Antilles: Biomechanical Analogue For Trace-Making Paleozoic Strophomenates?, Benjamin Dattilo, Tanya Del Valle, David Meyer, Aaron Morse
Benjamin F. Dattilo
The ability of Ordovician strophomenates Sowerbyella and Rafinesquina to move sediment and create moat-like depressions has led to questions about mechanisms. Anatomical studies suggest a gape of more than 45°, likely critical to trace-making abilities. Strophomenates are extinct, but thecidellinids are reasonably good analogues; they also gape widely and have a similar lophophore structure. They differ in their small size, 3 - 5 mm, lack of concavo-convex form, and by pedicle valve cementation. Nevertheless, their physiology could illuminate biomechanical constraints on strophomenate-sediment interactions. For this study, we analyzed 1 hour of video showing 30+ specimens collected with the fragment of …
The Brachiopod Trap: What Their Oldest (Upper Ordovician, Ohio) Failed Escape Burrows Tell Us About The Evolution Of Burrowing In Lingulids, Rebecca Freeman, Benjamin Dattilo, Aaron Morse, Michael Blair, Bryan Utesch, Steve Felton, John Pojeta
The Brachiopod Trap: What Their Oldest (Upper Ordovician, Ohio) Failed Escape Burrows Tell Us About The Evolution Of Burrowing In Lingulids, Rebecca Freeman, Benjamin Dattilo, Aaron Morse, Michael Blair, Bryan Utesch, Steve Felton, John Pojeta
Benjamin F. Dattilo
Infaunal organisms living in shallow marine settings are vulnerable to exhumation during storms or entombment by storm-deposited sediments. Cambrian–Early Ordovician lingulids included epifaunal as well as possible infaunal forms. However, many epifaunal forms became extinct during the Middle Ordovician, and Late Ordovician lingulids were similar in their infaunal habits and marginal habitats. Modern infaunal lingulids are able to reorient themselves after burial in sediments, but it is unclear when this ability evolved. Initial burrowing of juvenile lingulids, as well as re-burrowing of exhumed modern lingulids involves digging downwards and then back up in a u-shape, but successful escape burrowing involves …

North Atlantic Vibrio Vulnificus Surveillance From Postharvest Oysters At A Us Shellfish Processing Facility, Kenneth Lavalley, Joseph Dealteris, Michael Rice, Marta Gomez-Chiarri
Marta Gomez-Chiarri
Postharvest surveillance for Vibrio vulnificus by a commercial processing facility was conducted from May 2001 to September 2003. Harvest areas included the Delaware Bay, Long Island Sound and Prince Edward Island. Occurrence followed a seasonal distribution. Low densities were observed in June, increased through August, and became rare by September. Given the ubiquitous nature of marine Vibrios, it was not surprising to find V. vulnificus everywhere, which was investigated. Observations confirmed the importance of strict time/temperature and product handling practices by shellfish harvesters, dealers and processors. Mishandling led to a potentially dangerous and uncharacteristically high V. vulnificus observation.

Critical Thermal Minima Of Age-0 Australian Bass, Macquaria Novemaculeata, Fingerlings: Implications For Stocking Programmes, Cameron M. Leo, Lee J. Baumgartner, Daniel J. Bucher, Wayne Robinson
Dr Daniel J Bucher
Fishes are often stocked outside natural distribution ranges with inadequate information on target streams, particularly thermal regimes. Australian bass, Macquaria novemaculeata (Steindachner), is a catadromous species that is regularly stocked into upland reaches of rivers and impoundments in south-eastern Australia. Critical Thermal Minima (CTMin) were determined for age-0 Australian bass fingerlings with a mean fork length of 64.4 ± 0.4 mm and weighing 3.8 ± 0.8 g. Four treatments were used, including three replicate aquaria for each treatment. Fingerlings were acclimated at either 8 or 15 °C at densities of 15 fish in 56-L glass aquaria. Water temperatures were …

Selecting Zones In A Marine Park: Early Systematic Planning Improves Cost-Efficiency; Combining Habitat And Biotic Data Improves Effectiveness, H A. Malcom, E Foulsham, R L. Pressey, A Jordan, P L. Davies, T Ingleton, N Johnstone, S Hessey, Stephen Da Smith
Professor Stephen DA Smith
Systematic planning, using algorithm tools, can improve biodiversity representation in ‘no-take’ zones in a marine park while reducing costs of meeting conservation targets. The current zoning plan for the 870 km2 Solitary Islands Marine Park (SIMP), designed without algorithm tools, provides an example to compare the efficiency of zoning scenarios that include or ignore the existing zoning scheme and to assess the utility of habitat and/or biotic data for planning. Marxan was used to compare representation of habitat categories and a selection of fish species using 3 scenarios for ‘no-take’ sanctuary zones: 1) clean slate; 2) building on the …
