We show that the interlayer transport in a two-dimensional superconductor can reveal a peak in the temperature as well as the magnetic field dependence of the resistivity near the superconducting transition. The magnetotransport experiment was performed on the highly anisotropic misfit-layer superconductor (LaSe)1.14(NbSe2) with critical tempertaure Tc of 1.2 K. The effect is interpreted within the tunneling mechanism of the charge transport across the Josephson-coupled layers via two parallel channels - the quasiparticles and the Cooper pairs. Similar behavior can be found in the high-Tc cuprates but there it is inevitably interfering with the anomalous normal state. The upper critical magnetic field can be obtained from the interlayer tunneling conductance.
