Title

TF1104

Tabulate coral

Description

Stratigraphic Range

Ordovician to Permian

Taxonomy

Phylum: Cnidaria
Class: Anthozoa
Order: Tabulata

Distinctive Features

Tabulae
Colonial

Preservation

Mineral replacement of skeleton

Advanced notes

Due to the way that this specimen has been cut and polished, the tabulae are not immediately obvious. They are visible on parts of the slab, allowing for this to be identified as a tabulate coral.

You may recognise this specimen from the coffee table in the common room on the ground floor of the Earth Sciences Department. Have a go at identifying the other fossils in the table on your next coffee break!

Title

TF1103

Rugose coral

Description

Stratigraphic Range

Ordovician to Permian

Taxonomy

Phylum: Cnidaria
Class: Anthozoa
Order: Tabulata

Distinctive Features

Septa
Colonial
Columella
Polyps

Preservation

Mineral replacement of skeleton
Precipitation of minerals in spaces

Advanced notes

The presence of columella (central support structures) and septa allow identification of this fossil as a colonial rugose specimen. Columella are not present in tabulate corals as these are always colonial, and do not need the extra support.
Solitary rugose corals developed columella as an internal support structure, and it was retained for some colonial forms, such as this one.

Isastraea explanata

Subject

Scleractinian coral

Specimen Age

Jurassic

Location

Coral Rag, Upware, Cambridgeshire

Description

Species

Isastraea explanata (also Isastrea explanata)

Stratigraphic Range

Jurassic

Taxonomy

Phylum: Cnidaria
Class: Anthozoa
Order: Scleractinia
Genus: Isastrea

Distinctive Features

Title

TF1101

Halysites

Subject

Tabulate coral

Description

Stratigraphic Range

Silurian

Taxonomy

Phylum: Cnidaria
Class: Anthozoa
Order: Tabulata
Genus: Halysites

Distinctive Features

Halysites is a so-called 'chain coral'. Unsurprisingly it can be identified as it has a distinctive 'chain' appearance, each 'link' in the chain is a separate animal, all part of a larger colony.

Preservation

External mould
