Usually when in a chainsaw you find that the piston's intake skirt has shattered most times I found the cause to be that the intake skirt had gotten so worn that it finally gets so thin and weak that it will eventually shatter and leave lots of debris in the crankcase. This is almost always due to the saw have a poor air filter and sucking in lotsa dirt,which goes down the intake port and hits the intake skirt,wearing it away until it breaks,a few models were famous for that,Mag2 and earlyist 064's.
Usually the cylinder is ok,you just need to wash out the crankcase very well(filling it with fuel mix,spinning the crank around,then quickly flipping the saws and dumping it out,repeat until the fuel in the crankcase is clean) Then look closely for anywhere all that dirt was getting into the crankcase and fix it,often just a bad filter or not sealing well.
In a rare occasion something has gone down the intake port(like a loose throttle plate screw or something like that. The picture of your piston almost looks like maybe something got sucked in,check all those possibilities before running it again.
