Paracryptodira is an extinct group of reptiles in the clade Testudinata (which contains modern turtles and their extinct relatives), known from the Jurassic to Paleogene of North America and Europe. Initially treated as a suborder sister to Cryptodira, they were then thought to be a very primitive lineage inside the Cryptodira according to the most common use of the latter taxon. They are now often regarded as late-diverging stem-turtles, lying outside the clade formed by Cryptodira and Pleurodira. The paracryptodires are said to have phylogenic relationships, noted as primary subclades, within the Baenidae and Pleurosternidae. Within each subclade, lies many biodiverse turtles that are continuously being investigated and added to the fossil record. Paracryptodires are divided into three m

  • Els paracriptodirs (Paracryptodira) són un infraordre extint dels Testudines, l'ordre de rèptils que inclou les tortugues. Inicialment considerat com un subordre germà del grup Cryptodira, ara són tractats com un llinatge molt primitiu dins de Cryptodira d'acord amb l'ús més comú d'aquest últim tàxon. Alguns criptodirs prehistòrics una mica menys primitius (per exemple, les "tortugues banyudes", Meiolaniidae) així com les formes vivents formen el grup . * * * * (ca)
  • Paracryptodira es un infraorden extinto de tortugas (Testudines). Inicialmente considerado como un suborden hermano del grupo Cryptodira,​ ahora es tratado como un linaje muy primitivo dentro de Cryptodira de acuerdo al uso más común de este último taxón.​ Algunas criptódiras prehistóricas algo menos primitivas (por ejemplo, las "tortugas cornudas", Meiolaniidae) así como las formas vivientes conforman el grupo .​ * * * * , otro grupo de criptódiros prehistóricos que puede ser realmente una agregación parafilética, son a veces situados parcial o totalmente entre los paracriptódiros.

  • De Paracryptodira zijn een groep uitgestorven reptielen in de clade Testudinata (die moderne schildpadden en hun uitgestorven verwanten bevat), bekend van het Jura tot het Paleoceen van Noord-Amerika en Europa. (nl)
  • Paracryptodira (лат.) — клада вымерших черепах, живших во времена юрского — палеогенового периодов (167,7—37,2 млн лет назад). Систематики дискутируют, к какому объемлющему таксону относится эта клада: к подотряду скрытошейных черепах (Cryptodira), являясь примитивной линией внутри подотряда, или к самому отряду черепах, являясь сестринским таксоном Cryptodira.

  • Paracryptodira são uma infraordem já extinta de Testudines, uma ordem que está representada pelas tartarugas (marínhas e de água doce), pelos Jabuti (tartarugas terrestres) e pelos Cágados (de água doce).Inicialmente reconhecidos como uma subordem irmã de Cryptodira, a infraordem Paracryptodira é atualmente conhecida por ser uma linhagem bastante primitiva pertencente à subordem Cryptodira, de acordo com a utilização mais frequente deste último gênero. * * * * (pt)
