W. DROOGER In the July issue of The Micropaleontologist, Esteban Boltovskoy raised the question of the species concept and related problems in the study of foramninifera. His article clearly shows the disadvantages of space limitations, as it deals with so many topics that the schematic treatment is sometimes in danger of being misunderstood. Nevertheless, Boltovskoy's article may be very usef'ul for those who ignore the neonto- logical species and subspecies concepts. Some very valuable warnings are given, although their background has to be necessarily very vague. At the risk of being equally terse, I would like to comment on some of the points raised by Boltovskoy. -

QUICKE2 1 The Department of Organismal Biology and Anatomy, The University of Chicago, 1027 East 57th Street, Chicago, IL 60637-1508, USA ([email protected]; [email protected]) 2 Department of Biology, Imperial College at Silwood Park, Ascot, Berkshire SL57PY, UK and Department of Entomology, The Natural History Museum, Cromwell Road, London SW75BD, UK ([email protected]) (Received 29 November 2001; revised 28 August 2002; accepted 2 September 2002) ABSTRACT In an attempt to investigate differences between the most widely discussed hypotheses of early tetrapod relation- ships, we assembled a new data matrix including 90 taxa coded for 319 cranial and postcranial characters. We have incorporated, where possible, original observations of numerous taxa spread throughout the major tetrapod clades. A stem-based (total-group) definition of Tetrapoda is preferred over apomorphy- and node-based (crown-group) definitions. This definition is operational, since it is based on a formal character analysis. A PAUP* search using a recently implemented version of the parsimony ratchet method yields 64 shortest trees. Differ- ences between these trees concern: (1) the internal relationships of aı¨stopods, the three selected species of which form a trichotomy; (2) the internal relationships of embolomeres, with Archeria -
Glossary of Major Terms and Concepts
Glossary of Major Terms and Concepts The following terms and concepts form the core of much of this book. Generally, they appear in boldface type in the text. The chapters in which they are more fully discussed are also given. Acceleration: Faster rate of developmenral evenrs (at any level: cell, organ, individual) in the descendanr; produces peramorphie traits when expressed in the adult pheno type. (Chapters 1 and 2) Allometric heterochrony: Change in a trair as a function of size (as opposed to a function of age in " true" heterochrony); it is useful as adescriptor and can be inrerpretive considering that body size is often a beuer metric of " inrrinsic" age than chronologi cal age. The same categories apply as in " true" heterochrony, only the adjective "allometric" is prefixed: e.g. , " allometric progenesis" is when the descendant ter minates growth at a smaller size (as opposed to age) than the ancestor. (Chapter 2) Allometry: The study of size and shape, usually using biometrie data; the change in size and shape observed. Basic kinds of allometric change include the following. Com plex allometry: occurs when the ratio of the specific growth rates of the traits compared are not constant, a log-log plot comparing the traits will not yield a straight line (i.e., " k" in the allometric formula is inconstanr). Isometry: occurs when there is no change in shape with size increase; that is, when the traits being compared on a log-log plot yield a straight line with a slope (k in the allometric formula) that is effectively equal to 1. -
Phylogeny of Basal Tetrapoda
Stuart S. Sumida Biology 342 Phylogeny of Basal Tetrapoda The group of bony fishes that gave rise to land-dwelling vertebrates and their descendants (Tetrapoda, or colloquially, “tetrapods”) was the lobe-finned fishes, or Sarcopterygii. Sarcoptrygii includes coelacanths (which retain one living form, Latimeria), lungfish, and crossopterygians. The transition from sarcopterygian fishes to stem tetrapods proceeded through a series of groups – not all of which are included here. There was no sharp and distinct transition, rather it was a continuum from very tetrapod-like fishes to very fish-like tetrapods. SARCOPTERYGII – THE LOBE-FINNED FISHES Includes •Actinista (including Coelacanths) •Dipnoi (lungfishes) •Crossopterygii Crossopterygians include “tetrapods” – 4- legged land-dwelling vertebrates. The Actinista date back to the Devonian. They have very well developed lobed-fins. There remains one livnig representative of the group, the coelacanth, Latimeria chalumnae. A lungfish The Crossopterygii include numerous representatives, the best known of which include Eusthenopteron (pictured here) and Panderichthyes. Panderichthyids were the most tetrapod-like of the sarcopterygian fishes. Panderichthyes – note the lack of dorsal fine, but retention of tail fin. Coelacanths Lungfish Rhizodontids Eusthenopteron Panderichthyes Tiktaalik Ventastega Acanthostega Ichthyostega Tulerpeton Whatcheeria Pederpes More advanced amphibians Tiktaalik roseae – a lobe-finned fish intermediate between typical sarcopterygians and basal tetrapods. Mid to Late Devonian; 375 million years old. The back end of Tiktaalik’s skull is intermediate between fishes and tetrapods. Tiktaalik is a fish with wrist bones, yet still retaining fin rays. The posture of Tiktaalik’s fin/limb is intermediate between that of fishes an tetrapods.

From Sea to Slime: Evolution of Amphibians Late Devonian: Rhipidistians an Important Link: Tooth Structure Skeletal Modification
Late Devonian: Rhipidistians From Sea to Slime: Evolution of Amphibians Lungs were developed in two groups of lobe-finned fishes - Rhipidistians and lungfishes . The Rhipidistians are considered to be the ultimate ancestors of later land animals. Rhipidistians such as Eusthenopteron had evolved "land animal-like features": Eusthenopteron Skeletal Modifications An Important Link: Tooth Structure Labyrinthodont tooth Labyrinthodont tooth of Rhipidistian fish of early amphibian (Eusthenopteron) (Archegosaurus) Labyrinthodont tooth structure (with complexly infolded enamel) is shared between Rhipidistian fishes and the earliest amphibians. This strongly supports a close relationship between the two groups. 1 Late Devonian: Ichthyostega and Acanthostega -Ichthyostega was a cross between a fish and an amphibian -Ichthyostega had legs and walked and was a true tetrapod. -With true legs, it could live on land for extended periods. -The primitive amphibians like Ichthyostega had a special kind of skin that helped them retain bodily fluids and deter desiccation. -Stronger skeletons allowed the primitive amphibians to live more comfortably with the increased gravity on land. -Animals like Ichthyostega used their limbs for locomotion and their tails for balance. Ichthyostega Carboniferous to Permian Evolution of neck and ear · Amphibian nostrils became increasingly functional for breathing air. · Amphibians evolved "hands" and "feet" with five digits. · Amphibian tails became reduced in size. · Amphibian backbones grew stronger (this enabled amphibian bodies to grow bigger). · Amphibians obtained eardrums. -Fishes need limbs to support bodies and ears to hear sounds in the air. -Fins changed to limbs -Several bones of the skull changed to the shoulder bones -Tongue cartilage (part of the jaw in fish) became an ear bone. -
Silurian Thelodonts from the Niur Formation, Central Iran
Silurian thelodonts from the Niur Formation, central Iran VACHIK HAIRAPETIAN, HENNING BLOM, and C. GILES MILLER Hairapetian, V., Blom, H., and Miller, C.G. 2008. Silurian thelodonts from the Niur Formation, central Iran. Acta Palaeontologica Polonica 53 (1): 85–95. Thelodont scales are described from the Silurian Niur Formation in the Derenjal Mountains, east central Iran. The mate− rial studied herein comes from four stratigraphic levels, composed of rocks formed in a shallow water, carbonate ramp en− vironment. The fauna includes a new phlebolepidiform, Niurolepis susanae gen. et sp. nov. of late Wenlock/?early Lud− low age and a late Ludlow loganelliiform, Loganellia sp. cf. L. grossi, which constitute the first record of these thelodont groups from Gondwana. The phlebolepidiform Niurolepis susanae gen. et sp. nov. is diagnosed by having trident trunk scales with a raised medial crown area separated by two narrow spiny wings from the lateral crown areas; a katoporodid− type histological structure distinguished by a network of branched wide dentine canals. Other scales with a notch on a smooth rhomboidal crown and postero−laterally down−stepped lateral rims have many characters in common with Loganellia grossi. Associated with the thelodonts are indeterminable acanthodian scales and a possible dentigerous jaw bone fragment. This finding also provides evidence of a hitherto unknown southward dispersal of Loganellia to the shelves of peri−Gondwana.

06_250317 part1-3.qxd 12/13/05 7:32 PM Page 15 Phylum Chordata Chordates are placed in the superphylum Deuterostomia. The possible rela- tionships of the chordates and deuterostomes to other metazoans are dis- cussed in Halanych (2004). He restricts the taxon of deuterostomes to the chordates and their proposed immediate sister group, a taxon comprising the hemichordates, echinoderms, and the wormlike Xenoturbella. The phylum Chordata has been used by most recent workers to encompass members of the subphyla Urochordata (tunicates or sea-squirts), Cephalochordata (lancelets), and Craniata (fishes, amphibians, reptiles, birds, and mammals). The Cephalochordata and Craniata form a mono- phyletic group (e.g., Cameron et al., 2000; Halanych, 2004). Much disagree- ment exists concerning the interrelationships and classification of the Chordata, and the inclusion of the urochordates as sister to the cephalochor- dates and craniates is not as broadly held as the sister-group relationship of cephalochordates and craniates (Halanych, 2004). Many excitingCOPYRIGHTED fossil finds in recent years MATERIAL reveal what the first fishes may have looked like, and these finds push the fossil record of fishes back into the early Cambrian, far further back than previously known. There is still much difference of opinion on the phylogenetic position of these new Cambrian species, and many new discoveries and changes in early fish systematics may be expected over the next decade. As noted by Halanych (2004), D.-G. (D.) Shu and collaborators have discovered fossil ascidians (e.g., Cheungkongella), cephalochordate-like yunnanozoans (Haikouella and Yunnanozoon), and jaw- less craniates (Myllokunmingia, and its junior synonym Haikouichthys) over the 15 06_250317 part1-3.qxd 12/13/05 7:32 PM Page 16 16 Fishes of the World last few years that push the origins of these three major taxa at least into the Lower Cambrian (approximately 530–540 million years ago). -
A TRIBUTE in LOVING MEMORY Irina Diana Tarabac
A TRIBUTE IN LOVING MEMORY Irina Diana Tarabac (1970-2007) Irina Diana Tarabac dedicated her life to learning, teaching, and science – the field of her choice being linguistics. Among many brilliant scholars and scientists in the Linguistics Department at Stony Brook University, Irina stood out for many a reasons. Unfortunately, Irina left us too early in October 2007. After arriving to study at Stony Brook at 2002, Irina became an active member of the linguistic community in the metropolitan area of New York. She frequently attended seminars in the Linguistics Departments of NYU and the CUNY Graduate Center. Irina was dedicated to life-long learning, and she set extremely high standards for herself, her own research and her teaching responsibilities. She taught a morphology seminar in Bucharest and served as a TA for classes on many different topics at Stony Brook, including syntax, morphology, language philosophy, phonology, typology, and Semitic languages. She was a wonderful teacher and was very concerned about her students. Her dedication to linguistics didn’t leave her much time to pursue her hobbies, but whenever Irina found some time off, she enjoyed listening to symphonic music, reading good literature, visiting museums, and spending time with her friends. Irina earned a Master’s degree in Bucharest, Romania in 1996 and had studied and conducted research in the Netherlands between 1997 and 1999. Irina conducted research on well-known languages such as Dutch, Romanian, and Modern Greek as well as less-known languages such as Rapanui and Burushaki. Irina’s passing is a great loss to her family, her friends and the field of linguistics. -
The Devonian Tetrapod Acanthostega Gunnari Jarvik: Postcranial Anatomy, Basal Tetrapod Interrelationships and Patterns of Skeletal Evolution M
Transactions of the Royal Society of Edinburgh: Earth Sciences, 87, 363-421, 1996 The Devonian tetrapod Acanthostega gunnari Jarvik: postcranial anatomy, basal tetrapod interrelationships and patterns of skeletal evolution M. I. Coates ABSTRACT: The postcranial skeleton of Acanthostega gunnari from the Famennian of East Greenland displays a unique, transitional, mixture of features conventionally associated with fish- and tetrapod-like morphologies. The rhachitomous vertebral column has a primitive, barely differentiated atlas-axis complex, encloses an unconstricted notochordal canal, and the weakly ossified neural arches have poorly developed zygapophyses. More derived axial skeletal features include caudal vertebral proliferation and, transiently, neural radials supporting unbranched and unsegmented lepidotrichia. Sacral and post-sacral ribs reiterate uncinate cervical and anterior thoracic rib morphologies: a simple distal flange supplies a broad surface for iliac attachment. The octodactylous forelimb and hindlimb each articulate with an unsutured, foraminate endoskeletal girdle. A broad-bladed femoral shaft with extreme anterior torsion and associated flattened epipodials indicates a paddle-like hindlimb function. Phylogenetic analysis places Acanthostega as the sister- group of Ichthyostega plus all more advanced tetrapods. Tulerpeton appears to be a basal stem- amniote plesion, tying the amphibian-amniote split to the uppermost Devonian. Caerorhachis may represent a more derived stem-amniote plesion. Postcranial evolutionary trends spanning the taxa traditionally associated with the fish-tetrapod transition are discussed in detail. Comparison between axial skeletons of primitive tetrapods suggests that plesiomorphic fish-like morphologies were re-patterned in a cranio-caudal direction with the emergence of tetrapod vertebral regionalisation. The evolution of digited limbs lags behind the initial enlargement of endoskeletal girdles, whereas digit evolution precedes the elaboration of complex carpal and tarsal articulations.
