  The perturbative QCD calculation of heavy quark fragmentation into a heavy
meson is extended to predict fragmentation into heavy flavor baryons. This is
accomplished by implementing the quark-diquark model of the baryons. Several
diquark form factors are used to enable the integration over the virtual heavy
quark momentum. The resulting spin independent functions for charmed quarks to
fragment into charmed baryons with spin 1/2 and 3/2 are compared with recent
data. Predictions are made for the spin dependent fragmentation functions as
well, particularly for the functions $\hat{g}_1$ in the case of spin 1/2
baryons.
