(Tibiotarsus [fused shin and ankle bones] of Lumbrerornis rougieri [scale bar = 10 mm], from Bertelli et al., 2024)

Meaning of name: Lumbrerornis = Lumbrera Formation bird [in Greek]; rougieri = for Guillermo Rougier [Argentinian paleontologist and discoverer of the original fossil]

Age: Eocene (Lutetian)

Where found: Lumbrera Formation, Salta, Argentina

How much is known: A partial left hindlimb and an indeterminate bone fragment.

Notes: Lumbrerornis is the first bird to be named from the Lumbrera Formation. It is unclear exactly what type of bird it was, but it has some similarities to two groups of long-legged Eocene birds from the Northern Hemisphere, the European palaeotidids and the North American geranoidids, both of which appear to have been closely related to ostriches.

some games i enjoy a very normal amount!!

Result from the Pierre Shale formation #Paleostream.

We covered here mostly the Sharon Springs member which is, these days, it's own formation within the Pierre Shale group.

With this piece we finally have a classic bait ball piece in this series, although the bait ball animal, Stratodus, is certainly not a classic.
