Agnathan vertebrates in the Lower Silurian of Gotland, Sweden
Geologiska Föreningen i Stockholm Förhandlingar, 1990Abstract The vertebrate scale collections from the Telychian? (upper Llandovery) Lower Visby Beds to the Gorstian? (lower Ludlow) upper Klinteberg Beds mostly represent low diversity thelodont faunas. In the oldest part, the Lower Visby Beds, only one scale of each of the thelodont genera Loganellia and Thelodus has been found.

Conflicting interpretations of the Silurian agnathan, Jamoytius
Scottish Journal of Geology, 1984Synopsis Jamoytius kerwoodi White, a Middle Silurian agnathan from the Lesmahagow Inlier, central Scotland, has been the subject of considerable controversy since it was first described in 1946. In a recent review of earlier intepretations of Jamoytius and its affinities Forey and Gardiner (

Structure and Function of Cholinesterases from Agnathans and Cephalochordates
1998Jawed vertebrates possess two related cholinesterases (ChE’s), acetylcholinesterase (AChE, EC 3.1.1.7) and butyrylcholinesterase (BuChE, EC 3.1.1.8). AChE hydrolyzes acetylcholine at cholinergic synapses. The function of BuChE is unknown, but is suggested to play a role in growth and development, and to act as a scavenger of cholinergic toxins (1). The

Some Aspects of Hormonal Regulation of Metabolism in Agnathans
1985A short paper by Barrington, concerning the morphology of the endocrine pancreatic organ in the larval lamprey and its assumed influence on plasma blood sugar, appeared in 1942. For about twenty years this pioneer effort was not followed by additional research on the metabolic effects of the hormones in cyclostomes.

[The evolution of adaptive immunity system of Agnathan vertebrates].
Yi chuan = Hereditas, 2009All along peoples pay extensive attention on the origin and evolution of adaptive immunity system. Agnathans, taking lamprey as the representative, are generally thought at the edge of evolving the adaptive immunity system. Therefore, it is very significantly important to further study the mechanism of adaptive immunity of agnathans for revealing the ...

The anatomy of the agnathan brain and craniate phylogeny.
2009The central nervous system of hagfishes displays unique characteristics that are distinct from any other craniate neuroanatomic features. Whether these hagfish characters are general for all craniates, autapomorphies of hagfishes, or merely a derived state of the general cyclostome condition is still a matter of debate that relates to the question of ...
