“…A stage of > 124 ky dated by OSL was established by Gutiérrez et al (2015) in the Colorado piedmont (USA). The oldest talus atiron in the Iberian Peninsula is found in the Teruel depression, dated to 152 ± 17 ky with OSL (Peña- Monné et al 2022). Intermediate ages are more frequent, and in the Iberian Peninsula such atirons have been described towards the NE of the Henares River basin and dated to ca.…”

The cyclical evolution of the testimonial buttes in the central area of the Ebro depression (Los Monegros) is analysed. It is a semiarid environment that favours high erosive rates. The aim of this paper is to obtain an evolutionary model of the Jubierre hills that shows the environmental cycles represented by aggradational and degradative processes on the slopes that produced the present arrangement of talus flatiron rings. In the four studied cases, the talus relicts are composed of detritic material from a disappeared caprock pediment. Four slope stages (S4 to S1) formed under more stable climate conditions are identified. Older stages ages (S4 and S3) are estimated by comparison with other talus flatiron systems from the region. The S2 stage contains Bronze Age archaeological remains and the radiocarbon age obtained was 1608 − 1446 years cal BC (2σ), while S1 is younger. A climate genesis is established for these aggradational stages (S4 to S1). The active erosion of these hills led to a relief inversion and talus flatirons remain as the only features revealing the presence of the old hills and past human occupations.
