Taquetochelys decorata

Osteichthyes - Testudines - Araripemydidae

Taxonomy
Taquetochelys decorata was named by de Broin (1980). Its type specimen is MNHN-GDF 847, a partial shell (a series of shell fragments), and it is a 3D body fossil. Its type locality is Gadoufaoua (general), which is in an Aptian terrestrial sandstone in the Elrhaz Formation of Niger.

It was considered a nomen dubium by Sereno and ElShafie (2013).

Synonyms
  • Laganemys tenerensis was named by Sereno and ElShafie (2013). Its type specimen is MNN GAD28, a partial skeleton (a nearly complete articulated skull and postcranial skeleton lacking the left posterolateral corner of the carapace and plastron, a few anterior caudal vertebra), and it is a 3D body fossil. Its type locality is G94, Gadoufaoua, which is in an Aptian/Albian channel sandstone in the Elrhaz Formation of Niger.

    It was synonymized subjectively with Taquetochelys decorata by Pérez-García (2018).

P. C. Sereno and S. J. ElShafie 2013 (Laganemys tenerensis)Basal pleurodire of small size (adult carapace length approximately 15 cm), skull very elongate (length more than five times maximum width) with snout increasing in depth anteriorly; maxilla with long posterior process ventral to the cheek emargination; postorbital excluded from the temporal emargination by quadratojugal-parietal contact; parietal-squamosal contact along the temporal emargination; parietal with posterolateral process; dentary ramus gently arched ventrally with squared distal end (chin) in lateral view; nuchal V-shaped; neural 3 small and rectangular with long axis oriented transversely, neural 8 small and rectangular (long axis sagittal), and neural 9 absent; epiplastron J-shaped; mesoplastron present and pentagonal; main forelimb bones (radius, metacarpal 2–4) considerably shorter (45–60%) than comparable hind limb bones (tibia, metatarsal 2–4); and metacarpal 2 with medially divergent distal condyles.
