ABSTRACT In this paper we describe previously unpublished trionychid turtle material, consisting of numerous shell fragments, from two Late Cretaceous (Santonian—early Campanian) localities from Middle Asia and Kazakhstan (Central Asia in the U.S. tradition): Kansai (Tadjikistan) and Shakh-Shakh (Kazakhstan). This material can be attributed to two forms of trionychids present in both localities. One of them is the named species Trionyx riabinini Kuznetsov and Chkhikvadze, 1987, described from… 
NEW DATA ON THE SOFT-SHELLED TURTLES FROM THE UPPER CRETACEOUS KYRKKUDUK I LOCALITY OF SOUTHERN KAZAKHSTAN
We re-examine one previously described trionychid specimen (a posterior part of a carapace formerly attributed to Trionyx zakhidovi Khosatzky, 1966) and describe additional trionychid shell material
A New Soft-Shelled Trionychid Turtle of the Genus Khunnuchelys from the Upper Cretaceous Bostobe Formation of Kazakhstan
Previously unpublished trionychid turtle material from the Upper Cretaceous (Santonian—lower Campanian) Bostobe Formation from the Baybishe and Baykhozha localities in Kazakhstan is described. The
Cretaceous soft-shelled turtles (Trionychidae) of Mongolia: new diversity, records and a revision
TLDR
The results of both analyses show that Apalonina, which is a rather advanced and well-supported trionychid clade, or its closest sister taxon (stem-Apalonina), were present in the Late Cretaceous of Asia.
First Record of Soft-Shelled Turtles (Cryptodira, Trionychidae) from the Late Cretaceous of Europe
ABSTRACT Fossil soft-shelled turtles (Trionychidae) have so far been recognized in all continents except Antarctica, based largely on remains preserving their diagnostic sculptured shell bones. The

Abstract Turtles of the clade Pan-Trionychidae have a rich fossil record in the Old World, ranging from the Early Cretaceous (Hauterivian) to the Holocene. The clade most probably originated in Asia
Kappachelys okurai gen. et sp. nov., a New Stem Soft-Shelled Turtle from the Early Cretaceous of Japan
TLDR
This work interprets Kappachelys as a stem trionychid, a small turtle that exhibits a unique combination of three features: coarse and deep vermiculate sculpture on carpace; no scute sulci; and well-developed peripherals, and believes it could be ancestral to thetrionychids of the Kitadani Formation.

TLDR
Conchochelys from the Paleocene of North America shares with Khunnuchelys derived features of the palate and braincase, and the two genera may be members of a monophyletic clade of trionychids.

DISTRIBUTION AND BIOGEOGRAPHY OF NON-MARINE CRETACEOUS TURTLES
During the Cretaceous, non-marine turtles show strong patterns of provincialism, mirroring the pattern of land masses resulting from the breakup of Pangea since the Jurassic. These patterns are a

TLDR
The taxonomic diversity of Judith River Group trionychids is less than that of younger Maastrichtian and Paleocene assemblages from the Western Interior, largely because of the absence of plastomenine trionYchids in the JudithRiver Group assemblage.
