The Tambach Formation has produced S. sanjuanensis fossils of a similar quality to those of the Cutler Formation. For example, in 2000 Berman and his colleagues described the "Tambach Lovers", two complete and fully articulated skeletons of S. sanjuanensis fossilized lying next to each other (though it cannot be determined whether they were a couple killed during courtship).
