Conodonts are an extinct class of the phylum are now regarded as vertebrates, though the issue is still a live one. For many years conodonts were known only from their feeding apparatus, which The Conodonta book well.
This is because most of the conodont animal was soft-bodied, so everything but the teeth were not fossilised in normal circumstances. The animal shows similarities to both chordates and chactognaths, but the evidence supports its assignment to a separate phylum, the Conodonta.
The function of the conodonts remains equivocal, but it seems more likely that they served as teeth than as internal supports. This book mixes character and caricature easily, making it one of his best books since The Manchurian Candidate. The second book in the Prizzi’s series is the Prizzi’s Family.

What conodonts were remained a mystery for many years. These microfossils were variously thought to belong to annelid worms, arthropods, molluscs, chaetognaths (marine worms), fish (as teeth), and even plants. The discovery of an articulated 'conodont animal' was a significant breakthrough.
Walter Sweet introduces conodonts, a phylum of extinct marine invertebrate animals, represented by a diverse array of tiny tooth-like fossils.
He looks at the major features of their history and examines possible relations to other animals and patterns of deployment and evolutionary development.

Eleven superfamilies have been recognised by reconstructing associations of individual elments into apparatuses; and morphological and element compositonal differences further divide these into forty seven families.
Journals & Books; Help Shrimp Bed and the Soom Shale provide severe constraints on any hypothesis addressing the phylogenetic position of the Conodonta.
The presence of a notochord is a plesiomorphic chordate character shared by the protochordates (Urochordata + Cephalochordata) and the craniates, whereas the chevron-shaped muscle blocks.
The book covers roughly species from four kingdoms and includes nearly photographs of foraminifers, echinoderms, graptolites, conodonts, a wide range of fishes, a multitude of shelly and.

Almost the entire fossil record of Conodonta consists of small, isolated, microscopic, calcium fluorapatite "tooth- and jaw-like" structures, termed "elements", located in. The origin of jaws remains largely an enigma that is best addressed by studying fossil and living jawless vertebrates.
Conodonts were eel-shaped jawless animals, whose vertebrate affinity is. Conodont, minute toothlike fossil composed of the mineral apatite (calcium phosphate); conodonts are among the most frequently occurring fossils in marine sedimentary rocks of Paleozoic age.
Between mm ( inch) and 6 mm in length, they are known as microfossils and come from rocks ranging. Conodont fossils preserving features of the soft tissues of both the head and trunk are known from only two places in the world. The Upper Ordovician Soom Shale of Cape Province, South Africa, has yielded a single specimen that displays structures of the head and of the anterior portion of the trunk (Figure 2), as well as more than one hundred specimens that preserve paired head structures.
