These conclusions have proved controversial. There is now a consensus that conodonts belong within the chordates, but their position within the clade is...

Terrestrial invertebrate population studies in the Chernobyl exclusion zone, Ukraine

The Chernobyl reactor accident in April 1986 released some 3-6.10 TBq Cs and 2-4.10 TBq Sr to atmosphere. About half of this was deposited within 20 km of the site, leading to extensive death of trees and other biota, and the establishment of a human exclusion zone. High levels of contamination remain in this zone. Nonetheless, birch (Betula spp.) and willow (Salix spp.) have recolonised the fo...

Conodont anatomy, chordate phylogeny and vertebrate classification

Interpretations of conodont anatomy and affinity continue to generate controversy. Fossilized soft-tissue evidence indicates that conodonts possessed eyes, extrinsic eye muscles, a notochord, myomeres, a differentiated tail with fin radials, possible otic capsules and possible branchial structures. Indirect evidence suggests a differentiated brain and cartilaginous head skeleton. The multi-comp...
