A lamprey from the Cretaceous Jehol biota of China

  author={Mee-mann Chang and Jiangyong Zhang and Desui Miao},
Widespread nowadays in freshwater and coastal seas of the cold and temporal zones, lampreys are a jawless vertebrate group that has been in existence for more than 300 million years but left a meagre fossil record. Only two fossil lamprey species, namely Mayomyzon pieckoensis and Hardistiella montanensis, have been recognized with certainty from North American Carboniferous marine deposits. Here we report a freshwater lamprey from the Early Cretaceous epoch (about 125 million years ago) of… Expand
A lamprey from the Devonian period of South Africa
A marine/estuarine fossil lamprey from the Famennian (Late Devonian) of South Africa is reported, the identity of which is established easily because many of the key specializations of modern forms are already in place, evidence that agnathans close to modern lampreys had evolved before the end of the Devonian period. Expand
Palaeontology: Modern look for ancient lamprey
A recently discovered lampreys fossil dates from the twilight age of their supposed ancestors, and looks surprisingly modern, and is now joined by a well preserved fossil from the Devonian of South Africa, which is the oldest known lampreys. Expand
Early Jawless Vertebrates and Cyclostome Origins
The anatomy and physiology of lampreys and hagfishes are so different that it is difficult to reconstruct an ancestral morphotype of the cyclostomes, assuming that they are a clade, and there is no clear evidence of any fossil taxon that is neither a fossil hagfish nor a fossil lamprey, but would be more closely related to the Cyclostomes than to the gnathostomes.

Discovery of fossil lamprey larva from the Lower Cretaceous reveals its three-phased life cycle
The discovery of exceptionally preserved premetamorphic and metamorphosing larvae of the fossil lamprey Mesomyzon mengae from the Lower Cretaceous of Inner Mongolia, China are reported, indicating the three-phased life cycle in lampreys emerged essentially in their present mode no later than the Early Cret Jurassic. Expand
The remarkable fossils from the Early Cretaceous Jehol Biota of China and how they have changed our knowledge of Mesozoic life
Palaeontologists and others have been repeatedly amazed by reports of spectacularly well-preserved fossils from China, and one of the key sources has been the Jehol Biota of Liaoning, Hebei and InnerExpand
The taxonomy, phylogeny and distribution of lampreys
The phylogenetic relationships of the lampreys were similar in most respects to those obtained by subjecting molecular data for those species to Bayesian analyses, however, in contrast to the results of morphological analyses, the genera Eudontomyzon and Lampetra were not monophyletic when using molecular analyses. Expand
The evolution of lamprey (Petromyzontida) life history and the origin of metamorphosis
A review synthesizes findings and concludes that the ancestral lamprey life cycle followed a direct development, suggesting that the larval period was short and relatively limited if present at all, but that the juvenile included modern larval traits. Expand
Hagfish from the Cretaceous Tethys Sea and a reconciliation of the morphological–molecular conflict in early vertebrate phylogeny
By addressing nonindependence of characters, phylogenetic analyses recovered hagfish and lampreys in a clade of cyclostomes (congruent with the cyclostome hypothesis) using only morphological data, which potentially resolve the morphological–molecular conflict at the base of the Vertebrata. Expand
The Jehol Biota, an Early Cretaceous terrestrial Lagerstätte: new discoveries and implications
Although some progress has been made on the reconstruction of the paleotemperature at the time of the Jehol Biota, much more work is needed to confirm a possible link between the remarkable diversity of the biota and the cold intervals during the Early Cretaceous. Expand
A Mesozoic Pompeii: History of the Jehol Biota's Rise and Fall
The Jehol fauna was initially represented by a bony fish, concostracan and an insect, as a Lycoptera davidi–Eosestheria–Ephemeropsis trisetalis association, but since the researches of recentExpand


A second lamprey from the Lower Carboniferous (Namurian) of Bear Gulch, Montana (U.S.A.)
Abstract A second fossil lamprey is described from the Lower Carboniferous (Namurian) locality of Bear Gulch (Montana, U.S.A.), which had already yielded the type specimen of HardistiellaExpand
An exceptionally preserved Lower Cretaceous ecosystem
Findings include feathered theropod dinosaurs and early birds, which provide additional, indisputable support for the dinosaurian ancestry of birds, and much new evidence on the evolution of feathers and flight. Expand
The geological and biological environment of the Bear Gulch Limestone (Mississippian of Montana, USA) and a model for its deposition
The Bear Gulch Limestone (Heath Formation, Big Snowy Group, Fergus County, Montana, USA) is a Serpukhovian (upper Mississippian, Namurian E 2 b) Konservat lagerstatte, deposited in the CentralExpand
A proposal for the functional and phylogenetic significance of differences in the dentition of lampreys (Agnatha: Petromyzontiformes)
It is concluded that blood-feeding preceded flesh-feeding in ‘modern’ lampreys; endemic freshwater parasitic species typically ingest blood; the ability to feed on flesh developed in populations which had access to estuarine and marine hosts; and pre-Tertiary forms resembling contemporary lehthyomyzon unicuspsis could have given rise independently to both of the divergent and specialized genera of Southern Hemisphere lampreys.

First Fossil Lamprey: A Record from the Pennsylvanian of Illinois
A fossil record of lampreys has previously been unknown, but a new genus demonstrates the presence of this group in the Pennsylvanian, and the absence of hagfish characters in the fossil supports the view that the common ancestor of Lampreys and hagfishes lived prior to thePennsylvanian. Expand
Potential Fecundity of Landlocked Sea Lamprey Larvae, Petromyzon marinus, with Typical and Atypical Gonads
Recent observations on landlocked sea lamprey larvae from the Great Lakes basin have revealed highly atypical patterns of gonadal development, which compared current estimates of potential fecundity with those made several decades earlier before larval abundance was regularly reduced in streams by chemical treatment. Expand
Decay of Branchiostoma: implications for soft‐tissue preservation in conodonts and other primitive chordates
Decay experiments on the cephalochordate Branchiostoma lanceolatum (‘amphioxus’) demonstrate that the most decay resistant structures are the notochord sheath and the cartilaginous rods which support the gill bars, and cast light on the interpretation of a number of primitive fossil chordates.

Gonadal Variation in Great Lakes Sea Lamprey, Petromyzon marinus, Larvae
Examination of larvae from 15 different populations suggest the proportion of atypical larvae is currently much higher in streams tributary to the Great Lakes, than was previously observed. Expand
