Topic: Paramys


  
  Paramys - Wikipedia
Paramys is een primitief knaagdier uit de familie Ischyromyidae dat voorkwam tijdens het Eoceen.
Paramys ontwikkelde zich in Noord-Amerika en vervolgens verspreidde dit dier zich naar andere continenten.
Paramys was een eekhoornachtig dier van 60 cm lang met een aantal typische knaagdierkenmerken.

 AMNH Scientific Publications: Item 2246/2009
"The morphology of the external surface of the petrosal and its junction with the basioccipital in Paramys copei is described.
Sciuravus is set apart by the lack of a ventral petrosal sinus canal between the petrosal and basioccipital and by the facial nerve and stapedial artery sharing a common foramen in the petrosal.
European theridomyids, too, are not as primitive as Paramys but share with it and Sciuravus a ridge on the promontorium that separates the transpromontorial continuation of the internal carotid artery from the origin of the tensor tympani muscle.

 The Geologic History of Fossil Butte National Monument and Fossil Basin (Paleontology)
Paramys was relatively unspecialized but was diverse in the number of species.
Paramys was probably an arboreal form that did not look too unlike a modern squirrel and may have had a similar mode of life.
Species of Leptotomus, Paramys, Thisbemys, Microparamys, Sciuravus, Mysops, and Pauromys demonstrate that a wide range of adaptations of environments was exploited by the rodents.

 Judith A. Schiebout
The TT-Jacks Paramys is small (Figure 2), but there is little correspondence of comparable teeth with the small sample of P.
Rodents, represented by Paramys, have been suggested as an example of this phenomenon (Schiebout et al., 1988) and Coryphodon may also have been affected.
The late first occurrence of Paramys may reflect only that isolated rodent teeth are tiny, and that no screen washing has been done in the stratigraphic interval between Joe's Bonebed and TT-Jacks.

 scary squirrel world - WHERE DO SQUIRRELS COME FROM
Paramys sported a mostly squirrel-like skeleton but without the arboreal adaptations.
More significantly, Paramys happened upon the scene in the Paleocene and Protosciurus during the Oligocene...
This strongly suggests that someone or something pulled Paramys from the market, came up with a better model, and released it back into the environment an epoch later.

 PPS '96 - Assignment 1   (Site not responding. Last check: 2007-11-04)
The earliest and most primitive of the known rodents is the Paramys whose fossils have been found in Paleocene and Eocene sediments in North America.
The Paramys was like a large squirrel, with clawed feet for grasping and climbing and a long tail for balancing.
The subsequent evolution of the rodents has been difficult to study because of their many and complex adaptations; they have been the most difficult mammalian order to classify and their history is very incompletely known.

 Ischyromys - Wikipedia, the free encyclopedia
Ischyromys's hind legs were longer than the forelegs, which could be used for other means than walking.
Unlike most other mammals of its time, Ischyromys was arboreal (along with its relative Paramys).
It was a well-adapted climber that gradually beat out competition from rodent-like arboreal plesiadapid primates.

Paramys and its ischyromyid friends (late Paleocene) -- Generalized early rodents; a mostly squirrel-like skeleton but without the arboreal adaptations.
GAP: No cavy fossils are known between Paramys and the late Oligocene, when cavies suddenly appear in modern form in both Africa and South America.
However, there are possible cavy ancestors (franimorphs) in the early Oligocene of Texas, from which they could have rafted to South America and Africa.

 A CLADISTIC REVIEW OF THE SCIURAVIDAE (MAMMALIA:RODENTIA) AND IMPLICATIONS FOR RODENT PHYLOGENY   (Site not responding. Last check: 2007-11-04)
This study examines the Sciuravidae, an important but little-studied family of primitive Eocene rodents that has been postulated as ancestral to the Muroidea, Dipodoidea, Castoroidea, Geomyoidea, and Caviomorpha.
A cladistic analysis will be presented on relationships of all postulated sciuravid genera and primitive members of potential sister taxa, using Paramys and Cocomys as outgroups.
The analysis is based on dental and, where available, skull and postcranial material from fossils, casts, and published descriptions.

 Where to find fossils at Abbey Wood, The Fossil Collectors Guide
In 1999, the largest number of mammalian finds in one single excavation surprised many who felt the bed was beginning to thin out.
It was in fact this thinning that 9 teeth were found, Sparnacomys, Paramys pourcyensis and possibly Pseudoparamys.An upper left P4 and M2 of Wyonycteris was also found.

He walked around the back, and the other two jumped when they heard him squeal in delight.
They ran around to join him and they looked with huge grins at the pair of Paramys that were lying under a branch, nestled against each other.
One of the Paramys stirred, and looked up at the watchers, blinking.

 Heaton: Great Plains Ischyromys
Prior to my study, dentaries of the two genera were thought to be indistinguishable (Black, 1968; Wood, 1980).
Both the earliest (late Duchesnean, earliest Chadronian) and the latest (Orellan, Whitneyan) ischyromyine skulls have primitive musculature similar to Paramys, so these retain the original name Ischyromys.
Most ischyromyine skulls from Chadronian deposits have a highly derived jaw musculature that parallels the sciuromorphs and myomorphs, and these forms are referred to Titanotheriomys.

Africa, India, and Madagascar were probably isolated from the rest of the world, and although South America was also cut off, some mammals found their way there from North America to found the unique mammal fauna.
A key event of the later Paleocene was the way that the earliest rodents such as Paramys invaded North America from their first known habitats in Asia.
Their arrival in North America coincides with a fall in the numbers of the multituberculates and the local squirrel-like primates.

 Articles / Impact / The Origin of Mammals - Institute for Creation Research
As to their origin, Romer has said "The origin of the rodents is obscure.
When they first appear, in the late Paleocene, in the genus Paramys, we are already dealing with a typical, if rather primitive, true rodent, with the definitive ordinal characters well developed.
Presumably, of course, they had arisen from some basal, insectivorous, placental stock; but no transitional forms are known."

Tribosphenomys minutus (late Paleocene, 55 Ma) -- A newer discovery, a small Asian anagalid known from a single jaw found in some fossilized dung, still had rabbit-like cheek teeth, but had fully rodent-like ever-growing first incisors, probably the "ancestral stem" of the rodents (Discover, Feb 1995, page 22)
Paramys and ischyromyid group (late Paleocene) -- Generalized early rodents, mostly squirrel-like skeleton but without the arboreal adaptations
