We observe 69 ${}^{41}\mathrm{K}{\text{−}}^6\mathrm{Li}$ interspecies Feshbach resonances including 13 elastic $p$-wave resonances and 6 broad $d$-wave resonances of ${}^{41}\mathrm{K}$ atoms in different spin-state combinations at fields up to 600 G. Multichannel quantum-defect theory calculation is performed to assign these resonances and the results show perfect agreement with experimental values after improving input parameters. The observed broad $p$- and $d$-wave resonances display a fully resolved multiplet structure. They may serve as important simulators to nonzero partial-wave-dominated physics.
