ListContourPlot needs an array of z values as first input.
You gave it a List of 3D-coordinates, wich is different. 
ListContourPlot plots each point over its index in x and y direction.
If you want to plot your points you need to triangulate your points 
into an surface, or tell MMA otherwise how to interpolate between
your (probably) unsorted points.
