Because nearly all Mustelinae exhibit sexual size dimorphism, the largest archaeological specimens of N. macrodon were more likely male than female. [13][15], The sea mink was a marine mammal that lived around the rocky coasts of New England and the southernmost Maritime Provinces until it was hunted to extinction in the late 19th or early 20th century. Axis 1, which was interpreted as representing size differences, described 91% of the variation among the musteloid species. The sea mink produced a distinctive fishy odor, and had fur that was said to be coarser and redder than that of the American mink. It likely lived in semi-marine environments, such as coastal waters. It was nearly twice as large as the common American mink, and had a slightly redder hue, so was highly prized by hunters. D&D Beyond 1875 - The broad-faced potoroo was last recorded. Musteloids occupy nearly all continents, inhabit latitudes from the arctic to the sub-antarctic, and the superfamily is arguably the most species-rich in the Carnivora. It may have even evolved there, as Maine at that time would have been covered in glaciers, although the oldest known specimen only dates back to around 5,000 years; this could be due to the rising sea levels—older sea mink remains may be submerged underwater. [6][7] A study in 1911 by Frederic Brewster Loomis, an American paleontologist, concluded that the differences between the American mink and the sea mink were too minute to justify the latter's classification as a separate species, and he named it Lutreola vison antiquus. Unlike the archaeological specimens, the museum specimens of N. vison showed a normal distribution of ml (Anderson-Darling test, A = 0.203, P = 0.87). (13).—F:AM 50540–50543, 50545, 50546, 50548, 50549, 50551, 50553, 50555, 50562, 50566. Disproportionate extinction of South American mammals drove the asymmetry of the Great American Biotic Interchange. The last two recorded kills of a sea mink were made in Maine in 1880 near Jonesport, Maine, and Campobello Island, New Brunswick, in 1894, although the 1894 kill is speculated to be of large American minks. If significant (P < 0.1), the differences between allometric scaling of males and females are listed. Brachypsalis sp. [13] There were reports of unusually large mink furs being collected from Nova Scotia regularly. "For those animals unfortunate enough to be naturally rare in the wild for ecological or geographical reasons - the Falkland Island Fox and the North American Sea Mink, for example - total extermination came easily and quickly when their pelts were in demand by the fur trade." "For those animals unfortunate enough to be naturally rare in the wild for ecological or geographical reasons - the Falkland Island Fox and the North American Sea Mink, for example - total extermination came easily and quickly when their pelts were in demand by the fur trade." Summary of dental differences between sea mink and American mink, with acronyms of measurements as defined in Fig. For most analyses, especially those of average trends in the evolution of several dental features, measurements were converted to their natural logarithms (In) to linearize the allometry equation (Jolicoeur and Mosimann 1960). Vermeij listed a date of “about 1900.” Monachus tropicalis : Knudtson ( 67 ) noted that the last authenticated sighting was in 1952 on Serranilla Bank in the western Caribbean. Unavailable name, because it was preempted by macrodon. Conversely, its range may have been restricted solely to the New England coast, specifically the Gulf of Maine, or just to the nearby islands. (2000) obtained individuals of N. vison from nearly the full extent of this species' range, including Alaska, Pacific offshore islands, and the east coast of North America, my study only incorporated specimens from the continental United States and southern Canada (subspecies energumenos, letifera, mink, and vison). (10).—F:AM 25278, 25299, 25309, 25456, 25462, 25474, 27425, 27428, 83433, 104825. Dental structures also are implicated in mating, food acquisition, and food processing, the last 2 of which are important components of the ecological niche. If the coefficient of variation (CV) for these replicates was greater than 0.1, the most deviant measurement was discarded and retaken. The 1st principal component analysis axis, representing 91% of the variation, was interpreted as representing size differences among the various species, and the remaining axes as reflecting differences in shape. Discoveries include the richest known assortment of sea mink bones (Mead et al. The ml in the larger archaeological group, which contained 75 specimens, was larger than any N. vison measured (9.27–10.73 mm). The highly prized fur of the Sea Mink caused hunters to kill every single last one in order to retrieve the fur and make a profit out of it. [16] The sea mink may have reached that area by traveling up rivers, or may have been brought there by Native Americans. In the principal component analyses, these measurements were used to provide additional groups for comparison. A sharp surface contacts a smaller section of the food, concentrating the force and increasingly lacerating the food item until it is cut into smaller pieces (Popowics 2003).
