Based on $ab$ $initio$ calculations and low-energy effective $k{\cdot}p$model, we propose a type of Weyl nodal point-line fermion, composed of 0D Weylpoints and 1D Weyl nodal line, in ferromagnetic material Eu$_5$Bi$_3$. In theabsence of spin-orbital coupling (SOC), the spin-up bands host a pair of triplydegenerate points together with a unique bird-cage like node structure. In thepresence of SOC with (001) magnetization, each triplet point splits into adouble Weyl point and a single Weyl point accompanied by two nodal rings,forming two sets of Weyl nodal point-line fermions near the Fermi level. Thenovel properties of Weyl nodal point-line fermion are explored by revealing theunusual Berry curvature field and demonstrating the pinned chiral surfacestates with exotic Fermi arcs at different planes. Moreover, a large anomalousHall conductivity of -260 ($\hbar$/$e$)($\Omega$cm)$^{-1}$ parallel to [001]direction is predicted. Our work offers a new perspective for exploring noveltopological semimetal states with diverse band-crossing dimensions, andprovides an ideal material candidate for future experimental realiztion.
