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.).


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.

Natural Trap, Tali, Data

Friday 18 October 2013
In Table 1 are the original data (6 sheets) provided by John Howe. Most measurements were not taken in my way and moreover not in the same way by the people who took them (compare the values on the lateral condyle height on sheet I, II, III and IV, V, VI-1 to 14)). The same specimen (42639) is (...)

Natural Trap, Radii, Data

Friday 18 October 2013
In Table 1 are the original data (2 sheets) provided by John Howe but measured by a student who apparently made some mistakes. Some data appeared redundant, either because they originated from the right and left side of the same animal or because the same specimen was measured twice. In Table 2 (...)

Natural Trap Caballine, Text

Friday 18 October 2013
Caballine There are a fragmentary mandible, KU 47238 (Fig.1) and a better preserved one, UNSM 51079 (Fig.2,3) associated to a palate (Fig.4). Cups are present on all lower incisors of KU 47238 and on I1-I2 of UNSM 51079. The lower (Fig.5) and upper chek teeth are caballine. I refer (with (...)

Amerhippus cf. pseudaltidens The major part of Natural Trap equid fossils may be referred to A. pseudaltidens. There are few cranial remains but more than 800 limb bones. In addition, there are a few specimens larger or smaller than usual but with the same proportions; I suppose that they come (...)

Natural Trap, Large Amerhippus, Text

Friday 18 October 2013
LARGE AMERHIPPUS A fragmentary skull, KU 51330, resembles one specimen from Tarija, Bolivia: the basicranial proportions are similar, and like in most Amerhippus the muzzle is very wide (Fig.1). The upper premolars of KU 56806 are similar to another specimen from Tarija. I refer to the (...)
