Could be the oil pan gasket. Spray it off with some engine cleaner and investigate where it leaks from. take a couple of pictures and post those on here.There is also the oil pump that is in the front cover, driven from the front of the crankshaft. Oil passes in and out of the front cover through the timing cover gaskets which may have failed. A failed front crank seal will usually fling oil off the damper and soak the area.
