Palembert is located in the Quercy phosphorites urban area (South-west out of France) near the village from Caylus (Tarn-et-Garonne, France)
Procedure off Palembert. One remaining M2/ (Buddy 21); one remaining mandibular fragment with Yards/step 3 (Friend sixty); that left mandibular fragment that have Yards/2 and you can P/4 (Friend 62); one correct remote Meters/step three (Buddy 64).
Towards distal part, the talonid basin are buccolingually compacted and you will holds a small entoconid and a worn out hypoconid
Breakdown. The top of dentition regarding Palembertina deplasi late. gen. the fall of. sp. is only reported of the M2/ (Buddy 21; Shape 2I-J, Contour 3C). They holds five chief cusps. The paraconule is actually mesiolingual and you can contains good preparacristula linking the fresh new preparacristyla; the brand new metaconule is high and you can merchandise an initial and continued premetacristula, as well as a good postmetacristula joining the fresh postmetacristyla; this new protocone lacks a crest which is centrolingually arranged. The latest styles are really-pronounced: the newest buccal appearances try weakly crested having a cycle-instance and you may distally inclined mesostyle; the latest lingual appearances, distostyle and you can mediostyle, was remote and large. In the long run, the fresh new M2/ has actually obvious mesial and you will distal cingula.
The lower dentition of Palembertina deplasi aged P/4 and you may M/dos, a complete, unworn M/step three, and you can a damaged Yards/3. New top off P/4 (Buddy 62; Contour 2G-H) is actually brief and you can thin and you may presents around three fundamental cuspids: a massive protoconid, metaconid, and you may paraconid. With the mesial part of the tooth, the fresh hoe iemand een bericht te sturen op pussysaga paraconid was a little more likely lingually. A postprotoconulid is seen between your protoconid and hypoconid. This new morphology of your straight down molars is usually considering Meters/3 (Friend 60, Friend 64; Contour 2E-F, 2K, Figure 3d), by the worst conservation of your own Meters/dos (Pal 62; Profile 2G-H). The lower molars establish three lingual cuspids: a beneficial mesial metaconid, a sub-main metaconulid, and you can a distal entoconid. On trigonid, the brand new paraconid are small, and protoconid is really lingual. The newest talonid are highest that have a tiny centroconulid close to the metaconulid, and a great postendocentroconulid weakly expanded distolingually. The metaconulid try higher, close to the metaconid, and also the mediocristid was brief. A large area can be obtained between the metaconulid plus the entoconid. The fresh entoconid possess a circle-such as for instance figure which will be somewhat way more distal as compared to hypoconid. M/step 3 (Buddy 60, Friend 64; Profile 2E-F, 2K, Figure three-dimensional) introduce a huge hypoconulid, basin-formed and you may distal to the entoconid. It links towards remaining portion of the talonid by the prehypocristulid, hence suits the latest posthypocristulid and postentocristulid. More over, the latest posthypocristulid is actually weakly obvious and offered lingually. Eventually, the fresh mesial cingulid try large.
The newest protoconid therefore the metaconid try close to both, the brand new protoconid being a whole lot more mesial than the metaconid
This new mandibular morphology out of Palembertina deplasi nov. gen. late. sp. is actually reported in the quantity of the next premolar (Buddy 62; Profile 2G-H) mesially, on root of the mandibular angle (Friend 60; Contour 2E-F) distally. The mandible (Pal 62) merchandise a short diastema anywhere between P/2 and you may P/3 and two rational foramina with the lateral ramus, one to below the mesial part of P/dos and something underneath the mesial section of P/cuatro (Figure 2H). Brand new lateral ramus are gracile, seemingly superficial, and its own level is pretty ongoing involving the premolar town and you may the very last molar. A wide pit is available between your base of the ascending ramus in addition to distal margin out-of Yards/3 (Figure 2F). The latest angular apophysis isn’t maintained however, appears to be medially inclined; it’s mesially delimited by the a superficial incisura vasorum (Pal 60).
Statements. Gervais (1852) erected new variety Cainotherium courtoisii, and you may Stehlin (1906) next placed they from the genus Oxacron. Gervais (1852) explained and figured this new kinds according to the small sized cainotheriids specimens from La Debruge but did not establish an effective holotype. Depending on the International Password off Zoological Nomenclature, the name Oxacron courtoisii exists yet not valid; ergo, i define right here good lectotype and you will an excellent paralectotype to have Oxacron courtoisii, comparable to the materials of La Debruge to begin with realized of the Gervais (1852): leftover mandibular fragment having P/3-M/step 3 (plate XXXV, fig. 4) into the lectotype; leftover maxillary fragment with P4/-M3/ (dish XXXIV, fig. 6) to your paralectotype.
