New Rhamphorhynchus at the Field: Lauer Foundation Collection

The Lauer Foundation for Paleontology provided
this deep cut Rhamphorhynchus (Fig. 1) to the Field Museum, Chicago, USA. The foundation number is: #LF 1182. Photoshop helps get rid of the surface and deep cuts to see the bones without those distractions.

Due to its generic look,
the Lauer Foundation specimen enters the large pterosaur tree (LPT, 250 taxa) somewhere in the middle of this genus, distinct from all others, between the ROM specimen (first row, far right, Fig. 2) and the Imhof specimen (second row, far left, Fig. 2).

This wonderful and complete specimen
nests in the middle of the tested Rhamphorhynchus (Fig. 2) specimens (Fig. 3), outside the clade of the largest specimens (including the large and only juvenile, the Vienna specimen row 2, second from right)..
