  The quasi-2D Shastry-Sutherland model has remained topical in the field of
condensed matter physics for the last two decades, following the experimental
realization of the model in the material SrCu$_2$(BO$_3$)$_2$. Since then,
research into the Shastry-Sutherland system has revealed more nuanced physics
than initially predicted; recent theoretical works have even predicted a
quantum spin liquid phase may exist. Herein, we report on a new
Shastry-Sutherland lattice material, Yb$_2$Be$_2$GeO$_7$, of the rare-earth
melilite family RE$_2$Be$_2$GeO$_7$. We find, through SQUID magnetometry,
powder neutron diffraction, specific heat capacity, and muon spin relaxation,
that Yb$_2$Be$_2$GeO$_7$ lacks magnetic order and exhibits persistent spin
dynamics to at least 17 mK. We propose the Shastry-Sutherland lattice material
Yb$_2$Be$_2$GeO$_7$ as a candidate to host a quantum spin liquid ground-state.
