We observe the decays D*{sub s1} (2710){sup +} {yields} D*K and D*{sub sJ} (2860){sup +} {yields} D*K and measure their branching fractions relative to the DK final state. We also observe, in the D*K mass spectrum, a new broad structure at a mass of (3044 {+-} 8{sub stat}(+30/-5){sub syst}) MeV/c{sup 2} having a width {Lambda} = (239 {+-} 35{sub stat}(+46/-42){sub syst}) MeV. To obtain this result we use 470 fb{sup -1} of data recorded by the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} storage rings at the Stanford Linear Accelerator Center running at center-of-mass energies near 10.6 GeV.
