Some slightly older sketches of one of my dragon genera, the lyretails!

These guys come in a variety of species with many different behaviors, breeding practices, and so on. Interspecific hybrid lyretails can be born when different species mate with one another, but like most hybrids these dragons are sterile. At any rate hybrid lyretails are quite rare in the wild due to differences in breeding behaviors; this hasn't stopped dracologists from attempting to produce hybrids in controlled settings, however!
