. The crater was formed in the last 70 million years, perhaps in the late Cretaceous or early Tertiary Period. Spanning 6 kilometres, the crater sits at the southern end of a range of hills. The elevated position and concentric rings of Tin Bider suggest that its structure is complex

Complex crater
Complex craters are a type of large impact crater morphology.Above a certain threshold size, which varies with planetary gravity, the collapse and modification of the transient cavity is much more extensive, and the resulting structure is called a complex crater...
