Baena (turtle)

Baena is an extinct genus of baenid turtles.

Baenidae is an extinct family of paracryptodiran turtles known from the Early Cretaceous to Eocene of North America. While during the Early Cretaceous they are found across North America, during the Late Cretaceous they are only found in Laramidia, having disappeared from Appalachia. The majority of lineages survived the K-Pg Extinction, but the family was extinct by the latest Eocene. Compsemydidae and Baenidae are paracryptodira and turtle families.

Barremian

The Barremian is an age in the geologic timescale (or a chronostratigraphic stage) between 125.77 Ma (million years ago) and 121.4 ± 1.0 Ma (Historically, this stage was placed at 129.4 million to approximately 125 million years ago) It is a subdivision of the Early Cretaceous Epoch (or Lower Cretaceous Series).

Basal (phylogenetics)

In phylogenetics, basal is the direction of the base (or root) of a rooted phylogenetic tree or cladogram.

See Compsemydidae and Basal (phylogenetics)

Berriasian

In the geological timescale, the Berriasian is an age/stage of the Early/Lower Cretaceous.

See Compsemydidae and Berriasian

Berruchelus

Berruchelus is an extinct genus of paracryptodiran turtle from the Paleogene of western Europe. Compsemydidae and Berruchelus are paracryptodira.

Campanian

The Campanian is the fifth of six ages of the Late Cretaceous Epoch on the geologic timescale of the International Commission on Stratigraphy (ICS).

Cladogram

A cladogram (from Greek clados "branch" and gramma "character") is a diagram used in cladistics to show relations among organisms.

Compsemys

Compsemys is an extinct genus of prehistoric turtles from the Late Cretaceous and Paleocene of North America and possibly Europe. Compsemydidae and Compsemys are paracryptodira.

Cretaceous–Paleogene extinction event

The Cretaceous–Paleogene (K–Pg) extinction event, also known as the Cretaceous–Tertiary extinction, was the mass extinction of three-quarters of the plant and animal species on Earth approximately 66 million years ago.

Dinochelys

Dinochelys (from a reference to the Dinosaur National Monument Visitor Center and Greek chelys, turtle) is an extinct genus of paracryptodiran turtle from the Late Jurassic Morrison Formation.

Dorsetochelys

Dorsetochelys is an extinct genus of turtle from the Early Cretaceous of southern England and northwestern Germany.

Early Cretaceous

The Early Cretaceous (geochronological name) or the Lower Cretaceous (chronostratigraphic name) is the earlier or lower of the two major divisions of the Cretaceous.

Genus

Genus (genera) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses.

Glyptops

Glyptops is an extinct genus of pleurosternid freshwater turtle known from the Late Jurassic of North America.

Hațeg Island

Hațeg Island was a large offshore island in the Tethys Sea which existed during the Late Cretaceous period, probably from the Cenomanian to the Maastrichtian ages.

Helochelydridae

The Helochelydridae are an extinct family of stem-turtles known from fossils found in North America and Europe spanning the Early to Late Cretaceous. Compsemydidae and Helochelydridae are turtle families.

Implied weighting

Implied weighting describes a group of methods used in phylogenetic analysis to assign the greatest importance to characters that are most likely to be homologous.

Kallokibotion

Kallokibotion is an extinct genus of stem-turtle from the Upper Cretaceous (Maastrichtian, 86–66 million years ago), known from fossils found in Romania.

Kimmeridgian

In the geologic timescale, the Kimmeridgian is an age in the Late Jurassic Epoch and a stage in the Upper Jurassic Series.

Late Jurassic

The Late Jurassic is the third epoch of the Jurassic Period, and it spans the geologic time from 161.5 ± 1.0 to 145.0 ± 0.8 million years ago (Ma), which is preserved in Upper Jurassic strata.

Maastrichtian

The Maastrichtian is, in the International Commission on Stratigraphy (ICS) geologic timescale, the latest age (uppermost stage) of the Late Cretaceous Epoch or Upper Cretaceous Series, the Cretaceous Period or System, and of the Mesozoic Era or Erathem.
