  abstract = {{A}ssociations between impact structures and meteorite occurrences are rare and restricted to very young structures. {M}eteorite fragments are often disrupted in the atmosphere, and in most cases, meteorite falls that have been decelerated by atmospheric drag do not form a crater. {F}urthermore, meteorites are rapidly weathered. {I}n this context, the finding of shatter cones in {J}urassic marly limestone in the same location as a recent (105 +/- 40 ka) iron meteorite fall near the village of {A}goudal ({H}igh {A}tlas {M}ountains, {M}orocco) is enigmatic. {T}he shatter cones are the only piece of evidence of a meteorite impact in the area. {T}he overlap of a meteorite strewn field with the area of occurrence of shatter cones led previous researchers to consider that the meteorite fall was responsible for the formation of shatter cones in the context of formation of one or several small (<100 m) impact craters that had since been eroded. {S}hatter cones are generally not reported in association with subkilometer-diameter impact craters. {H}ere, we present new field observations and an analysis of the distribution and characteristics of shatter cones, breccia, and meteorites in the {A}goudal area. {E}vidence for local deformation not related to the structural {H}igh {A}tlas tectonics has been observed, such as a vertical to overturned stratum trending {N}150-{N}160. {N}ew outcrops with exposures of shatter cones are reported and extend the previously known area of occurrence. {T}he area of in situ shatter cones (similar to 0.15 km(2)) and the strewn field of meteorites are distinct, although they show some overlap. {T}he alleged impact breccia is revealed as calcrete formations. {N}o evidence for a genetic relationship between the shatter cones and the meteorites can be inferred from field observations. {T}he extent of the area where in situ shatter cones and macrodeformation not corresponding to {A}tlas tectonic deformation are observed suggest that the original diameter of an impact structure could have been between at least 1-3 km. {F}or typical erosion rates in the {A}tlas region (similar to 0.08 cm yr(-1)), the period of time required for the erosion of such a structure (1.25-3.75 {M}a) is much larger than the age of the meteorite fall. {T}his line of reasoning excludes a genetic link between the shatter cones and the meteorite fall and indicates that the observed shatter cones belong to an ancient impact structure that has been almost entirely eroded.},
