Bathonian

In the geologic timescale the Bathonian is an age and stage of the Middle Jurassic.

Benthos

Benthos, also known as benthon, is the community of organisms that live on, in, or near the bottom of a sea, river, lake, or stream, also known as the benthic zone.

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.

Egertonodus

Egertonodus is an extinct genus of shark-like hybodont fish. Asteracanthus and Egertonodus are Cretaceous cartilaginous fish, Hybodontiformes, Jurassic cartilaginous fish and Prehistoric cartilaginous fish genera.

Hybodontiformes

Hybodontiformes, commonly called hybodonts, are an extinct group of shark-like cartilaginous fish (chondrichthyans) which existed from the late Devonian to the Late Cretaceous.

Hybodus

Hybodus (from ύβος, 'crooked' and ὀδούς 'tooth') is an extinct genus of hybodont that lived from the Middle Triassic to the Late Cretaceous periods. Asteracanthus and Hybodus are fossil taxa described in 1837, Hybodontiformes, Jurassic cartilaginous fish, Prehistoric cartilaginous fish genera and taxa named by Louis Agassiz.

Incertae sedis

of uncertain placement or problematica is a term used for a taxonomic group where its broader relationships are unknown or undefined.

Louis Agassiz

Jean Louis Rodolphe Agassiz FRS (For) FRSE (May 28, 1807 – December 14, 1873) was a Swiss-born American biologist and geologist who is recognized as a scholar of Earth's natural history.

Middle Jurassic

The Middle Jurassic is the second epoch of the Jurassic Period.

Solnhofen Limestone

The Solnhofen Limestone or Solnhofen Plattenkalk, formally known as the Altmühltal Formation, is a Jurassic Konservat-Lagerstätte that preserves a rare assemblage of fossilized organisms, including highly detailed imprints of soft bodied organisms such as sea jellies.

Strophodus

Strophodus is an extinct genus of durophagous hybodont known from the Triassic to Cretaceous. Asteracanthus and Strophodus are Cretaceous cartilaginous fish, Hybodontiformes, Jurassic cartilaginous fish and taxa named by Louis Agassiz.

Tithonian

In the geological timescale, the Tithonian is the latest age of the Late Jurassic Epoch and the uppermost stage of the Upper Jurassic Series.

See Asteracanthus and Tithonian

Tubercle

In anatomy, a tubercle (literally 'small tuber', Latin for 'lump') is any round nodule, small eminence, or warty outgrowth found on external or internal organs of a plant or an animal.

See Asteracanthus and Tubercle

Valanginian

In the geologic timescale, the Valanginian is an age or stage of the Early or Lower Cretaceous.
