A new species of Lower Carboniferous holocephalan chondrichthyan, Delphyodontos dacriformes, is described from two fetal specimens. The well-developed slashing and piercing dentition, enlargement of the abdominal region, and fecal material indicate the probable evolution of intrauterine oophagy and viviparity in Paleozoic Chondrichthyes. 

Reproduction in Middle Triassic actinopterygians; complex fin structures and evidence of viviparity in fossil fishes

New well-preserved specimens of Peltopleurus lissocephalus Brough, 1939, a small actinopterygian fish of the Alpine Middle Triassic, are described. Some of them show a highly modified anal fin, with

Repeated fluctuations in environmental parameters through time, producing fine-scale spatial and temporal non-equilibrium, were probably ultimately responsible for the maintenance of this broad-scale high diversity community.

Coelacanths from the Middle Triassic Luoping Biota, Yunnan, South China, with the Earliest Evidence of Ovoviviparity

The fossil record of coelacanths is patchy, with very few taxa known from the Triassic of Asia. We report here two new genera and species of coelacanths from the Luoping Biota, a recently found site

Superfoetative viviparity in a Carboniferous chondrichthyan and reproduction in early gnathostomes

The fossilized remains of two specimens of Harpagofututor volsellorhinus from the Upper Mississippian of Montana now provide the first direct evidence of matrotrophic live birth in a Palaeozoic chondrichthyan and of superfoetation in an extinct fish.

Viviparity: The Maternal-Fetal Relationship in Fishes

The maternal-fetal trophic relationships in each of the major groups of fishes are systematically reviewed and Pertinent anatomical, histological, ultrastructural, developmental, physiological, and biochemical studies are considered.

Earliest fossil evidence for protective pigmentation in an actinopterygian fish

These markings provide the earliest evidence in primitive fossil actinopterygians for (respectively) countershading and the use of disruptive markings to break up the body outline, two of the most common protective coloration strategies in Recent fishes.

The Bear Gulch Limestone Member is proposed herein as the new name for the Bear Gulch Beds of central Montana, USA. This member contains articulated and exceptionally well preserved fossils.

Ecomorphology of the Mississippian fishes of the Bear Gulch Limestone (Heath formation, Montana, USA)

These analyses lend new insight into the adaptive radiations of Chondrichthyes and Osteichthyes subsequent to the Upper Devonian mass extinctions.

It is concluded that the species-specific fetal dentition is functional in obtaining nutrition in the oviduct, in contrast to previous suggestions.

There is found to be strong evidence that the chimaeroids are derived, through the Jurassic myriacanthids and allied forms, from a Palaeozoic group which includes the Permian Menaspis and whose most primitive known genus is Deltoptychius.

Latimeria, the Living Coelacanth, Is Ovoviviparous

It is concluded that Latimeria is ovoviviparous, a gravid female containing five advanced young, averaging 317.8 millimeters long, which suggests that gestation may require more than a year not an unexpected length of time in view of the tremendous size of the ripe egg.
