Lungfish and the Long Defeat

open access: yesDiversity, 2023
Australia has an excellent fossil record of lungfish that begins in the Devonian and includes many species in Tertiary and Quaternary deposits. The extant Australian lungfish, Neoceratodus forsteri, occurs in Pliocene deposits, but is now restricted to a

Tell Us a Story Granddad: Age and Origin of an Iconic Australian Lungfish

open access: yesFrontiers in Environmental Science, 2022
The modern discovery of the Australian lungfish (Neoceratodus forsteri) by European settlers in 1870 was considered one of the most important events in natural history by leading international scientists and naturalists of that time.

Cardiovascular actions of lungfish bradykinin in the unanaesthetised African lungfish, Protopterus annectens

open access: yesComparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2002
Bradykinin (BK) isolated from plasma of the African lungfish, Protopterus annectens, contains four amino acid substitutions compared with BK from mammals (Arg1 → Tyr, Pro2 → Gly, Pro7 → Ala, Phe8 → Pro).

Morphometric analysis of lungfish endocasts elucidates early dipnoan palaeoneurological evolution

open access: yeseLife, 2022
The lobe-finned fish, lungfish (Dipnoi, Sarcoptergii), have persisted for ~400 million years from the Devonian Period to present day. The evolution of their dermal skull and dentition is relatively well understood, but this is not the case for the ...

The rapid evolution of lungfish durophagy

open access: yesNature Communications, 2022
It is unclear how Lungfishes evolved durophagy, the consumption of hard prey, despite being the longest lineage of vertebrates with this feeding mechanism. Here, the authors describe exceptionally preserved fossils of Youngolepis from the Early Devonian,

Age structure of the Australian lungfish (Neoceratodus forsteri). [PDF]

open access: yesPLoS ONE, 2019
The Australian lungfish has been studied for more than a century without any knowledge of the longevity of the species. Traditional methods for ageing fish, such as analysis of otolith (ear stone) rings is complicated in that lungfish otoliths differ ...

A Metapopulation Model to Assess Water Management Impacts on the Threatened Australian Lungfish, Neoceratodus forsteri

open access: yesFishes
The Australian lungfish, Neoceratodus forsteri, is one of the world’s oldest vertebrate lineages, with a slow life-history and threatened status, requiring immediate conservation efforts.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates. [PDF]

open access: yesBiol Rev Camb Philos Soc
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Relaxation of Natural Selection in the Evolution of the Giant Lungfish Genomes. [PDF]

open access: yesMol Biol Evol, 2023
Nonadaptive hypotheses on the evolution of eukaryotic genome size predict an expansion when the process of purifying selection becomes weak. Accordingly, species with huge genomes, such as lungfish, are expected to show a genome-wide relaxation signature

Living animals for comparison in studies of Mesozoic fossils. [PDF]

open access: yesResearch & Knowledge, 2017
Lungfish are timeless, starting in the Devonian and still found today. Unfortunately this does not mean that biologists and palaeontologists agree about the functional anatomies of dipnoans.
