The phylogeny of early gnathostomes provides an important framework for understanding one the most significant evolutionary events, origin and diversification jawed vertebrates. A series recent cladistic analyses have suggested that placoderms, extinct group armoured fish, form a paraphyletic basal to all other We revised expanded this morphological data set, notably by sampling autapomorphies in similar way parsimony-informative traits, thus ensuring (unlike existing sets) satisfied...
Jaws from the jawless Until a fossil called Entelognathus was found to contain tripartite jaw few years ago, it believed that skeletons of early osteichthyans (bony fish), ancestors all vertebrates, were derived independently those earlier placoderms (so-called fish). Zhu et al. now describe second Silurian placoderm more securely bridges toothlike plates development jawed condition ultimately led three-boned in modern vertebrates (see Perspective by Long). This finding upends traditional...
A series of recent studies recovered consistent phylogenetic scenarios jawed vertebrates, such as the paraphyly placoderms with respect to crown gnathostomes, and antiarchs sister group all other vertebrates. However, some relationships within have remained controversial, positions Entelognathus, ptyctodontids, Guiyu-lineage that comprises Guiyu, Psarolepis Achoania. The revision dataset in a study reveals modified hypothesis, which shows these conflicts were sourced from few inadvertent...
The Early Devonian sarcopterygian Styloichthys changae provides substantial information to resolve the phylogenetic relationships of early sarcopterygians. Its dermal bones show a cosmine surface with relatively large pores and unique histological condition, which is essential understanding evolution dermoskeleton in However, more detailed on this taxon needed. Here, we present new data about morphology histology scales S. based two semi-articulated specimens. bear parallel ridges their...
A 409-million-year-old predatory fish provides unique insights into the early evolution of modern lobe-finned fishes.
Abstract Innovations relating to the consumption of hard prey are implicated in ecological shifts marine ecosystems as early mid-Paleozoic. Lungfishes represent first and longest-ranging lineage durophagous vertebrates, but how when various feeding specializations this group arose remain unclear. Two exceptionally preserved fossils Early Devonian lobe-finned fish Youngolepis reveal origin specialized lungfish mechanism. has a radically restructured palate, reorienting jaw muscles for optimal...
The pectoral and pelvic girdles support paired fins limbs, have transformed significantly in the diversification of gnathostomes or jawed vertebrates (including osteichthyans, chondrichthyans, acanthodians placoderms). For instance, changes accompanied transition to limbs as some osteichthyans (a clade that contains vast majority vertebrates--bony fishes tetrapods) ventured from aquatic terrestrial environments. fossil record shows early (e.g., Lophosteus, Andreolepis, Psarolepis Guiyu)...
Abstract A new genus and species of tooth‐plated lungfish, Sinodipterus beibei gen. et sp. nov., is described from the Qujing Formation (Middle Devonian, late Eifelian) Zhaotong, Yunnan, China. The form resembles Dipterus in skull table, but differs its tooth‐plate: cosmine‐like tissue absent near midline, tooth rows fewer number (7 to 8) less divergent radiating, no reparative dentine layers. Phylogenetic analysis Devonian lungfish based on a dataset 150 characters 33 taxa indicates that...
Abstract Scale morphology and squamation play an important role in the study of fish phylogeny classification. However, as scales earliest osteichthyans or bony fishes are usually found a disarticulated state, research into patterns has been limited. Here we quantitatively describe scale oldest articulated osteichthyan, 425-million-year-old Guiyu oneiros , based on geometric morphometrics high-resolution computed tomography. Based cluster analysis specimens, present pattern which divides...
Qiao, T. & Zhu, M., 13.4.2015. A new Early Devonian lungfish from Guangxi, China, and its palaeogeographic significance. Alcheringa 39, xxx–xxx. ISSN 0311-5518A species of Cathlorhynchus (Dipnorhynchidae, Dipnoi) is described based on a mandible the marine Yukiang Formation (early Emsian, Devonian) southern China. It resembles type Cathlorhynchus, C. trismodipterus, in that anterior portion internal median septum terminates abruptly does not contact dermal bones ventrally. The Chinese form,...
Here the posterior cranial portion of tetrapodomorph Tungsenia from Lower Devonian (Pragian,~409 million years ago) Yunnan, southwest China, is reported for first time. The pattern skull roof and morphology otoccipital region neurocranium are described in detail, providing precious insight into combination characters earliest known to date. cranium displays a mosaic features previously linked either basal dipnomorphs such as Youngolepis (e.g., well-developed subjugular ridge, strong adotic...
A new genus and species of tooth-plated lungfishes, Dianodipterus huizeensis gen. et sp. nov., is described from the Qujing Formation (late Eifelian, Middle Devonian) Huize County, Qujing, north-eastern Yunnan, China. It differs other lungfishes in small proportion tooth-bearing part on pterygoid (less than one-quarter), extensively developed anteromedial edentulous portion pterygoid, tooth rows few number (only four). Phylogenetic analysis reveals that more plesiomorphic Dipterus, yet...
