Indocoelacanthus
species of fish (fossil)
Indocoelacanthus is an extinct genus of prehistoric freshwater coelacanth from the early-mid Jurassic of India. It contains a single species, I. robustus from the Toarcian-aged upper Kota Formation of Andhra Pradesh. The holotype specimen, consisting of an almost complete head and trunk squamation, was found in riverine sediments in the Pranhita-Godavari Valley at Boraigudem limestone ridge, about 30 kilometers southeast of Sironcha. In addition to the holotype, several other referred specimens consisting of the caudal fin, fin rays, and neural arches have also been identified. All specimens are preserved in the museum of the Indian Statistical Institute.
Its taxonomic placement has long been uncertain, with it initially being described in the Coelacanthidae, and having an unstable taxonomic position in later analyses. A comprehensive review in 2025 identified it as a basal member of the Mawsoniidae, a widespread coelacanth group throughout much of the Mesozoic.
It is the largest known fish in the Kota Formation, reaching an estimated total length of 70 centimetres (2.3 ft).
The public source identifies “Indocoelacanthus” as species of fish (fossil). This brief keeps that definition visible, then builds a research path around Indocoelacanthus, species and fish.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Indocoelacanthus”, the useful work is to connect “species of fish (fossil)” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 19, 2026. The linked authority identifier is Q6025689. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2025.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
