Bearing destruction. Any idea what caused this pattern?

Hey gang,

We recently found bearing material in the sump of the #15 race engine.

Upon inspection I saw some bearing wear that looks a little strange to me. As you'll see in the pictures, there are a number of "spot wear" areas that seem counter-intuitive to me. Any ideas what sort of failure would cause this.

Sure seems like oil-pressure in general then exacerbated by stuff plugging up the oil-journals, but I know the oil-levels were good and pressures were fine the whole time (according to the data logs anyway.)
