Hymenopteran cocoons are complex structures constructed from silk by larvae and exhibit a wide range of morphologies, compositions, and textures. The recognition of the most relevant characters of modern cocoons is important ...

The Miocene continental deposits in the Orera area, Calatayud–Daroca Basin, are composed of red and brown mudstones deposited in the dry mudflat, sepiolite and dolomicrites deposited in periodically desiccated alkaline ...

Specimens of Fictovichnus gobiensis, Celliforma curvata, Celliforma rosellii, Celliforma germanica and Celliforma isp. were collected from paleosol horizons in a fluviolacustrine succession near Santiago Yolomécatl town, ...

Invertebrate trace fossils from the late Miocene Cerro Azul Formation (La Pampa, Argentina) are described and compared with known paleosol ichnofacies. The formation is a loess succession punctuated by numerous calcareous ...

Numerous isolated fossil bee cells and other trace fossils are documented from the Santa Cruz Formation (Santa Cruz, Argentina). The trace fossils are described from paleosols of 7 coastal localities. The paleosols are ...

The ichnogenus Rebuffoichnus was created by Roselli in 1987 to include a single ichnospecies, R. casamiquelai. In this contribution, this ichnotaxon is redescribed and compared with similar trace fossils attributed to ...

The Cretaceous (Mercedes Formation) and Paleogene (Queguay Formation) deposits cropping out in W and S Uruguay comprise two terrestrial limestone units that are very rich in trace fossils. The study of these units permits ...

More than 4000 insect trace fossils collected in recent years from Pliocene deposits at Laetoli in northern Tanzania provide new insights on early hominin palaeoenvironments. These trace fossils include: Fictovichnus ...

Three new records of insect pupation chambers are reported from two localities in the Cretaceous Chubut Group of Patagonia, Argentina: from Sierra Nevada, a new and older ichnospecies of Rebuffoichnus, R. sciuttoi isp. ...
