[1] T. grangeri is known from a single partial femur from Eocene deposits in Inner Mongolia,[1] while T. peregrinus was found in France.

[2] The holotype and only known specimen of Telecrex grangeri, AMNH 2942, is a partial right femur collected from the Eocene Irdin Manha Formation.

The distal end and part of the trochanter are missing.

In 1974, the holotype was reexamined by Storrs Olson, who concluded that it was in fact an early relative of guineafowl, a family previously only known from Africa and Europe.

[1] The holotype of Telecrex peregrinus, NHMW 1988/28/1 was collected near Lalbenque in Lot, France at some point in the nineteenth century and described as a new species by Mlíkovský in 1986.
