Palaeoecological and palaeoenvironmental influences revealed by long-bone palaeohistology: the example of the Permian branchiosaurid Apateon - The Terrestrialization Process: Modelling Complex Interactions at the Biosphere-Geosphere Interface - page 141

Fig. 3. (a)-(c) Skeletochronological evidences in the cortical assemblages arranged from the youngest individual to the
oldest (as oriented by the curved arrows) of diaphyseal thin sections, made in limb bones of Apateon taxa from the
Permian of the Saar-Nahe Basin, Germany (scale bars of arrangements: 0.1 mm; of detailed thin sections: 0.5 mm) and
(d) their distribution. (a) Apateon pedestris from Odernheim (humeral cortices of SMNS 54963, SMNS 56136 B, SMNS
54988; femoral cortices of SMNS 56136 A, SMNS 54980, SMNS 54981); femoral (F) and humeral (H) sections bring
the same skeletochronological information and can therefore be used without any discrimination to assess the age of
individuals. (b) Apateon caducus from Erdesbach (humeral or femoral cortices of GPIM-N 1589, GPIM-N 1680,
GPIM-N 1560, GPIM-N 1297, GPIM-N 1572, GPIM-N 1602); and (c) Apateon pedestris from Niederkirchen (humeral
or femoral cortices of GPIM-N 1471, SMNS 55016, SMNS 55019, SMNS 55018, SMNS 55017, SMNS 55015).
