The largest fossil rodent.
The discovery of an exceptionally well-preserved skull permits the description of the new South American fossil species of the rodent, Josephoartigasia monesi sp. nov. (family: Dinomyidae; Rodentia: Hystricognathi: Caviomorpha). This species with estimated body mass of nearly 1000kg is the largest yet recorded. The skull sheds new light on the anatomy of the extinct giant rodents of the Dinomyi...
متن کاملThe anatomy of the world's largest extinct rodent.
Phoberomys is reported to be the largest rodent that ever existed, although it has been known only from isolated teeth and fragmentary postcranial bones. An exceptionally complete skeleton of Phoberomys pattersoni was discovered in a rich locality of fossil vertebrates in the Upper Miocene of Venezuela. Reliable body mass estimates yield approximately 700 kilograms, more than 10 times the mass ...
متن کاملFossil Occurrence of Murine Rodent (Nesokia indica) in the Sudan.
A specimen of the murid rodent Nesokia indica has been recovered from a late Paleolithic archeological site in the Sudan. This is a range 1200 km south of the site of any known occurrences, and it indicates a different environment near the Nile River than that which exists at the present time. The late Paleolithic water table is inferred to have been more stable, allowing for permanent moist soil.
متن کاملThe largest among the smallest: the body mass of the giant rodent Josephoartigasia monesi.
Body mass in extant rodents covers more than four orders of magnitude, from a few grams up to 40 kg on average in the capybara (Hydrochaeris hydrochaeris; Silva & Downing 1995). However, rodents have been much bigger in the past. The South American fossil rodent, Phoberomys pattersoni (Sanchez-Villagra et al. 2003), found in northwestern Venezuela (Mones 1980; Horovitz et al. 2006) had an estim...
متن کاملAlgorithm for finding the largest inscribed rectangle in polygon
In many industrial and non-industrial applications, it is necessary to identify the largest inscribed rectangle in a certain shape. The problem is studied for convex and non-convex polygons. Another criterion is the direction of the rectangle: axis aligned or general. In this paper a heuristic algorithm is presented for finding the largest axis aligned inscribed rectangle in a general polygon. ...
