We find constraints on heavy, stable, strongly interacting massive particles (X) from searches for anomalous nuclei containing them, formed during primordial nucleosynthesis. Using existing data, we obtain a limit on the abundance ratio $C_X\equiv n_X/n_B$ in the range of $3\times 10^{-8}$ to $3\times 10^{-13}$ for masses up to 10 TeV if the $X-N$ interaction is sufficiently strong to bind in low Z nuclei. We also find a rough lower limit on the $X-N$ interaction that implies binding in nuclei with $A\geq 200$ over much of the $M_X$ range of interest, and address the relative abundance of such anomalous nuclei on Earth.
