  We explore different skyrmion types in the lowest Landau level of graphene at
a filling factor $\nu=\pm 1$. In addition to the formation of spin and valley
pseudospin skyrmions, we show that another type of spin-valley entangled
skyrmions can be stabilized in graphene due to an approximate SU(4) spin-valley
symmetry that is affected by sublattice symmetry-breaking terms. These
skyrmions have a clear signature in spin-resolved density measurements on the
lattice scale, and we discuss the expected patterns for the different skyrmion
types.
