Vertebrate/Invertebrate Trackways
2009
The Ichnology Workshop held in 1998 in Bornholm, DK, evidenced significant differences between approaches used for studying vertebrate and invertebrate ichnites. In particular, trackways are used more in invertebrate ichno-studies than in vertebrate studies. This is due to the intrinsic characteristics of each category, primarily the multiple consequences of the order of magnitude gap in sizes, the opportunity to have more taxonomic information of the trackmaker with vertebrate ichnites, the usefulness of correlations with biotopes and facies with invertebrate ichnites, and practical parameters such as the probability of findings. That vertebrate and invertebrate ichnologists exchange ideas…
Ichnocoenoses à Isopodichnus furcosus nov. ichnosp. dans le Permien du Bassin de Lodève (Massif Central, France)
1994
Resume Une nouvelle ichnoespece Isopodichnus furcosus est decrite. Elle represente des traces de repos faites probablement par des Branchiopodes notostraces. Frequente dans les formations de Rabejac et du Salagou du bassin de Lodeve, elle est caracterisee par l'existence de structures paires generalement bifides, parfois trifides. Celles-ci pourraient correspondre a l'empreinte des premiers appendices thoraciques, longs et ramifies chez les Triopsides ou Apodides a qui est attribuee Isopodichnus furcosus nov. ichnosp. La presence de niveaux a Isopodichnus furcosus nov. ichnosp. dans les formations rouges supraconglomeratiques de la serie permienne renforce la these du developpement de l'ari…
