We studied the chronology of LAG formation and validated the method for estimate age inArgenteohyla siemersi inhabiting the humid Chaco of Argentina. In addition, we determinedwhether well-expressed growth marks are formed in A. siemersi when raised during one yearin laboratory, to determine whether formation is genetically or environmentally based.Individuals increased 84.51% in BM and 52.47% in SVL after one year of growth in thelaboratory. Two out of eight individuals that survived at the end of the experiment showedwell-expressed growth marks. Overall, we confirm the reliability of the skeletochronology inestimating age of this specie and reinforce the hypothesis thta, the LAG formation is ultimately caused by a general intrinsic (genetic) control.
