Les amateurs de Chevaux, curieux de leur évolution, trouveront ici quelques articles publiés à leur intention dans la rubrique « Diffusion des connaissances ».

Toutefois la majeure partie du site, toujours en construction, est destinée à des spécialistes et fournit des informations (sytème de mesures, mesures, illustrations, photographies, commentaires, bibliographie) concernant l’ostéologie des Equidés. Pour le moment, c’est surtout les Equidés actuels et quelques Equus fossiles (Equus, Allohippus, Plesippus) qui sont documentés.
En ce qui concerne les Hipparions au sens large, mes données sur les formes d’Amérique du Nord (Merychippus, Cormohipparion, etc.) sont disponibles (en anglais) ainsi que celles sur certains Hipparions de l’ex-Union Soviétique, de France et de Grèce.

Mode d’emploi.

Les numéros (1, 2, 3, etc.) dans les tableaux font référence à des mesures décrites dans les rubriques « Outils – Système de mesures pour les os et les dents d’Equus (et d’Hipparions) ». Chaque os est figuré avec les légendes corespondantes, mais il faut cliquer sur les vignettes pour que le dessin apparaisse en taille normale.
La rubrique « Outils » contient aussi des explications pratiques concernant des méthodes d’étude (diagrammes de Simpson, estimations de hauteurs au garrot, différenciation des premières phalanges antérieures et postérieures, etc.).

WELCOME.

Most of this site is, and will be, devoted to equids from Merychippus to extant Equus. The information (metric data, photographs, bibliographic references) is given in order to help research specialists or students with their work. Some publications (in « Diffusion des Connaissances ») are intended for a broader public.
The main linguage of this site is French but many articles were translated in English (in particular those in « Tools » concerning methods of measurements).

Instructions for use.

Numbers (1, 2, 3, etc.) inside the tables refer to measurements described in « Tools - System of measurements for Equus (or Hipparion) bones and teeth » where corresponding illustrations and captions may be found for each bone (you have to click on the reductions to make them appear full-size).

The rubric « Tools » contains also practical explanations of techniques such as Simpson’s ratio diagrams, or « recipes » for calculating the withers height or for differenciating anterior and posterior phalanges.

Kuruksai, Abstract

Friday 16 April 2021 by Véra Eisenmann
Allohippus pamirensis was a large and robust species with a cranium resembling that of Khapry (ZIN 31078). The upper molars had unusually - for Allohippus - long protocones and the lower - unusually for Allohippus - shallow ectoflexids. A larger skull with a longer muzzle belonging to a very (...)


Kuruksai, Other Limb bones

OTHER LIMB BONES (Tables 7 to 13) A proximal fragment of Calcaneum (Fig. 28) is probably associated with the large posterior Ph1. Measurements were reproduced from Sharapov 1986.


Kuruksai, First Phalanges

Friday 16 April 2021 by Véra Eisenmann
FIRST PHALANGES (Table 6, Figures 26 and 27) Most posterior Ph1 are robust and and resemble the average posterior Ph1 of Allohippus vireti from Saint-Vallier, France. PIN 3120-329 is slender, possibly associated with the slender MT no N°, and has some similarities with the posterior Ph1 PO 132 (...)


Kuruksai, Metapodials

Friday 16 April 2021 by Véra Eisenmann
METACARPALS (Table 4) There are three different morphologies. Most specimens have wide and rather shallow distal ends (Fig. 12). Some of them can be seen on Figure 13. A distal fragment of MC from Montopoli is the closest I could find. Two specimens have deep proximal ends (Fig. 14). (...)


Kuruksai, Cheek teeth

Friday 16 April 2021 by Véra Eisenmann
UPPER CHEEK TEETH (Table 3) Their morphology (Fig. 7, 8, 9) is usual for Allohippus, except for the longer protocones on molars. The size of PIN 3120-501 is very large. LOWER CHEEK TEETH The double knot is typically Allohippine but the shallow vestibular froove on molars is not (Fig. 10, 11). (...)


Kuruksai, Introduction

Friday 16 April 2021 by Véra Eisenmann
THE EQUIDS FROM KURUKSAI Loc. 73 (TADJIKISTAN, RUSSIA) There have been several interpretations of the number and systematic status of these equids believed to be older than the Olduvai Episode. The most recent (Forsten and Sharapov, 2000) accepts the presence of one large and one small (...)


Kuruksai, Crania and Mandibles

Friday 16 April 2021 by Véra Eisenmann
CRANIA (Table 1) Two crania (PIN 3120-319 and 360) belong to the same species (Fig. 1 and 2). They are very similar to the cranium ZIN 31078 from Khapry (Fig. 3). PIN 3120-320 (Fig. 4) differs by the shortness of its palate may still belong to the same taxon. But PIN no N° is much larger and (...)
