Figure 1 in The body size, age structure, and growth of Bosc's fringe-toed lizard, Acanthodactylus boskianus (Daudin, 1802)
Figure 1. Cross-sections (18 µm thick) at the diaphysis level of a phalange of juvenile (A) and male (B) Acanthodactylus boskianus. A) Four-year-old juvenile, 45.14 mm body length. Four LAGs were observed in the periosteal bone. B) Eight-yearold male, 79.86 mm body length. Eight LAGs were observed in the periosteal bone (arrow heads). Endosteal resorption and endosteal bone were present. Periphery (black arrow) was not regarded as a LAG (m.c. = marrow cavity, r.l. = reversal line, e.r. = endosteal resorption, e.b. = endosteal bone).

FIGURE 10 in Morphology and multilocus phylogeny of the Spiny-footed Lizard (Acanthodactylus erythrurus) complex reveal two new mountain species from the Moroccan Atlas
FIGURE 10. Distribution of Acanthodactylus montanus (squares) and Acanthodactylus lacrymae (diamonds) based on specimens examined in this study. Coloured dots represent specimens of the three main phenotypes (none is monophyletic in the mtDNA or nDNA trees) in Morocco based on Bons and Geniez 1995. Specimens with the "bellii" phenotype in the High Atlas are almost certainly montanus and lacrymae. White symbols represent specimens tentatively identified as A. montanus (square) or A. lacrymae (diamond, see text). The continuous white lines represent the currently known distribution of the new species while dotted white lines represent possible extensions of the distribution if tentative identifications are correct. The dotted dark blue line represents the southernmost extension of confirmed IM clade specimens based on our field sampling.

The blue asterisks highlight haplotypes of the sample from Ouaourioud (IM clade), located only 10 km from the Tislit population (EHA clade).
