Jurapteryx recurva

Reptilia - Theropoda

Taxonomy
Archaeopteryx recurva was named by Howgate (1984) [type is the Eichstätt specimen]. Its type specimen is JM 2257, a skeleton (complete skeleton), and it is a compression fossil. Its type locality is Workerszell, Eichstätt, which is in a Tithonian lagoonal/restricted shallow subtidal limestone in the Altmühltal Formation of Germany. It is the type species of Jurapteryx.

It was recombined as Jurapteryx recurva by Howgate (1985); it was synonymized subjectively with Archaeopteryx lithographica by Paul (1988), Senter and Robins (2003) and Padian (2004).

Diagnosis
ReferenceDiagnosis
M. E. Howgate 1984The following major differences serve to identify the new
species.
(1) The teeth are more gracile and recurved.
(2) The specimen is one-third smaller than the other specimens of Archaeopteryx.
(3) The distal elements of the pes are proportionately longer.
(4) The pubic symphysis is short.

The following more problematic differences, if confirmed, would serve to
establish a distinct genus for the Eichstatt specimen.
(5) The pubis is very slightly opisthopubic or vertical.
(6) The lack of an ossified furcula.
