We show the hyperbolic and complex function field versions of Lang’s conjecture for smooth projective surfaces S having a fibration f:S→C with orbifold base an orbifold curve of general type. The fibre multiplicities defining the orbifold base are non-classical, and simply-connected surfaces S can occur. Also, it is not possible in general to reduce to the easy case where C itself is a curve of general type by a finite étale cover c:S′→S. We leave open the arithmetic version of Lang’s conjecture, which rests on an orbifold version of Mordell’s Conjecture, consequence of the ABC-conjecture, but apparently not of the proofs of Falting’s result.
