“…Fishes currently inhabiting waters in New England traveled from a refugium or multiple refugia to the newly formed rivers. There is trace fossil evidence suggesting that the recolonization following deglaciation was rapid, as soon as 75 years after the ice recession ( Peteet et al 1993 ; Benner et al 2008 , 2009 ; Knecht et al 2009 ).…”

During the last ice age, much of North America far south as 40°N was covered by glaciers (Hewitt 2000). About 20,000 years ago, as the glaciers retreated, the hydrologic landscape changed dramatically creating waterways for fish dispersal. The number of populations responsible for recolonization and the regions from which they recolonized are unknown for many freshwater fishes living in New England and southeastern Canada. The Blacknose Dace,Rhinichthys atratulus, is one of the freshwater fish species that recolonized this region. We hypothesize that the earliest deglaciated region, modern-day Connecticut, was recolonized byR. atratulusvia a single founding event by a single population. In this paper, we test this hypothesis phylogenetically with regard to the major drainage basins within Connecticut. The mitochondrial DNA exhibits low nucleotide diversity, high haplotype diversity, and a dominant haplotype found across the state. A small percentage of individuals in the Housatonic drainage basin, however, share a haplotype with populations in New York drainage basins, a haplotype not found elsewhere in Connecticut's drainage basins. We calculated a range for the rate of divergence for NADH dehydrogenase subunit 2 (nd2) and control region (ctr) of 4.43–6.76% and 3.84–8.48% per million years (my), respectively. While this range is higher than the commonly accepted rate of 2% for mitochondrial DNA, these results join a growing list of publications finding high rates of divergence for various taxa (Peterson and Masel 2009). The data support the conclusion that Connecticut as a whole was recolonized initially by a single founding event that came from a single refugium. Subsequently, the Housatonic basin alone experienced a secondary recolonization event.

“…As noted above, HITCHCOCK (1865) considered Lunulipes obscurus to be the work of a myriapod, and LULL (1915) considered it to be the work of a crustacean. A significant amount of neoichnological work has been done on myriapods and various aquatic crustaceans since HITCHCOCK and LULL conducted their studies (e.g., TRUSHEIM 1931;TASCH 1969;DAVIS et al 2007;KNECHT et al 2009;EISMAN & CHARNEY 2010). None of the trackways produced by the animals that were studied, however, strongly resembles Lunulipes obscurus.…”

“…Hammersburg, Hasiotis & Robison (2018) , Häntzschel (1975) , Miller (1996) and Pemberton, MacEachern & Gingras (2007) all supported classic Acripes as a junior synonym of Diplichnites ; the issue of synonymy is beyond the scope of this paper, but we note at least that the tracks in fossils that Gand et al (2008) called A. multiformis differ from SGDS 1290 in the same ways that Diplichnites tracks do (see above). Lastly, Knecht et al (2009 : figs. 5 and 6) also illustrated traces made by extant notostracans ( Fig.…”

New invertebrate trace fossils from the Lower Jurassic Moenave Formation at the St. George Dinosaur Discovery Site at Johnson Farm (SGDS) continue to expand the ichnofauna at the site. A previously unstudied arthropod locomotory trace, SGDS 1290, comprises two widely spaced, thick, gently undulating paramedial impressions flanked externally by small, tapered to elongate tracks with a staggered to alternating arrangement. The specimen is not a variant of any existing ichnospecies, but bears a striking resemblance to modern, experimentally generated crayfish walking traces, suggesting a crayfish or crayfish-like maker for the fossil. Because of its uniqueness, we place it in a new ichnospecies, Siskemia eurypyge. It is the first fossil crayfish or crayfish-like locomotion trace ever recorded.
