This next image portrays the timing of different depositional events around the time of the Antler Orogeny. You can see that the Arc Volcanism continued throughout the time that the Antler was created. You can also see that the sediment found in the Antler Allochthon were experiencing active deposition until ~360ma. The filling of the foredeep then starts ~355ma, suggesting that the material had been thrust over the sinking continental margin. By ~350ma, we find sediments overlapping the Antler Orogeny, suggesting that it had been significantly eroded. The dates in this figure are old, and though we do not need to know the exact numbers right now, it is important to think about the different forms of geologic evidence available for constraining when certain events happened.
