Therapsida

Therapsida is a clade comprising a major group of eupelycosaurian synapsids that includes mammals and their ancestors and close relatives.

See Angelosaurus and Therapsida

Thoracic vertebrae

In vertebrates, thoracic vertebrae compose the middle segment of the vertebral column, between the cervical vertebrae and the lumbar vertebrae.

See Angelosaurus and Thoracic vertebrae

Tibia

The tibia (tibiae or tibias), also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two bones in the leg below the knee in vertebrates (the other being the fibula, behind and to the outside of the tibia); it connects the knee with the ankle.

See Angelosaurus and Tibia

Tooth

A tooth (teeth) is a hard, calcified structure found in the jaws (or mouths) of many vertebrates and used to break down food.

See Angelosaurus and Tooth

Triceps surae muscle

The triceps surae consists of two muscles located at the calf – the two-headed gastrocnemius and the soleus.

See Angelosaurus and Triceps surae muscle

Trichasaurus

Trichasaurus is an extinct genus of caseid synapsids. Angelosaurus and Trichasaurus are prehistoric synapsid genera.

See Angelosaurus and Trichasaurus

Trochanter

A trochanter is a tubercle of the femur near its joint with the hip bone.

See Angelosaurus and Trochanter

Trochanteric fossa

In mammals including humans, the medial surface of the greater trochanter has at its base a deep depression bounded posteriorly by the intertrochanteric crest, called the trochanteric fossa.

See Angelosaurus and Trochanteric fossa

Type species

In zoological nomenclature, a type species (species typica) is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen (or specimens).
