T.J.R. Scholz presented some mammal-like reptile fossils (Class Synapsida) from rocks of the Beaufort Group at Victoria West to Dr Robert Broom* at the South African Museum, Cape Town, during 1907. Broom regarded one of these, which he named Galechirus Scholtzi after the collector, as the most important addition to the museum's vertebrate fossil collection that year, as "this little animal for the first time throws a clear light on the origin of the Therocephalian reptiles". He described the specimen in the Transactions of the South African Philosophical Society that same year. Another of the interesting discoveries donated by Scholz was the skeleton of a small aquatic reptile somewhat resembling Mesosaurus, which Broom named Heleosaurus scholtzi. The taxonomic position of both these fossils has remained uncertain.
In 1929 T.J.R. Scholz, presumably the same person, was reappointed as a member of the Transvaal Asylum Board for a further period of three years.
