The coelacanth was long considered a "living fossil" because scientists thought it was the sole remaining member of a taxon otherwise known only from fossils, with no close relations alive, [8] and that it evolved into roughly its current form approximately 400 million years ago. [1]
The coelacanth — a giant weird fish still around from dinosaur times — can live for 100 years, a new study found. ... were thought extinct until they were found alive in 1938 off South Africa.
Latimeria is a rare genus of fish which contains the two only living species of coelacanth. It includes two extant species: the West Indian Ocean coelacanth (Latimeria chalumnae) and the Indonesian coelacanth (Latimeria menadoensis). They follow the oldest known living lineage of Sarcopterygii (lobe-finned fish and tetrapods), which means they ...
The West Indian Ocean coelacanth[6] (Latimeria chalumnae) (sometimes known as gombessa, [2][7] African coelacanth, [8] or simply coelacanth[9]) is a crossopterygian, [10] one of two extant species of coelacanth, a rare order of vertebrates more closely related to lungfish and tetrapods than to the common ray-finned fishes.
Marjorie Eileen Doris Courtenay-Latimer (24 February 1907 – 17 May 2004) was a South African museum official, who in 1938, brought to the attention of the world the existence of the coelacanth, a fish thought to have been extinct for 65 million years. Marjorie Courtenay-Latimer discovered this coelacanth, formerly only seen in fossils ...
Living fossil. The coelacanths were thought to have gone extinct 66 million years ago, until a living specimen belonging to the order was discovered in 1938. A living fossil is an extant taxon that phenotypically resembles related species known only from the fossil record. To be considered a living fossil, the fossil species must be old ...
The Indonesian coelacanth (Latimeria menadoensis, Indonesian: raja laut), also called Sulawesi coelacanth, [3] [4] is one of two living species of coelacanth, identifiable by its brown color. It is listed as vulnerable by the IUCN , [ 4 ] and it was quickly given protected status under Indonesian National Law Number 7/1999 after its discovery ...
Scleracanthus is an extinct genus of prehistoric coelacanth lobe-finned fish. [1] [2] [3] It lived during the Early Triassic epoch in what is now Spitsbergen, Svalbard.[4] [3]The type and only species, Scleracanthus asper, was collected from the Lusitaniadalen Member of the Vikinghøgda Formation and is therefore Smithian (early Olenekian) in age.
