Pleurodictyum is a favorite coral of mine and now I have specimens from the Devonian of Bolivia in my collection. Below are three examples of Pleurodictyum amazonicum corals from the Belen formation. All three are casts of the original fossils found in nodules. The original calcium carbonate skeletons have long since dissolved away and only the mud filled voids are preserved. Despite this the fossils are still identifiable due to the somewhat unique growth pattern of the genus.Specimen #1 [...]

This is a gastropod fossil called Platyceras bistrami from the Belen formation (Devonian, Emsian stage) of Bolivia. It seems to be distinguished from other species by the undulating surface of it's shell. This is just a cast of the shell but the ripples are preserved well. Also, P. bistrami (when I write it that way it makes me think of Pastrami) has a tighter coil to it's shell than other species.This specimen was found south of La Paz, Bolivia and I purchased it off of

I posted in an earlier blog entry about some Trilobite fossils I had from Bolivia. At the time I could not tell what the genera was of them because there were no labels. Well I found the specimen below in a box with some older E-bay purchases and it has a label calling it Metacryphaeus sp. (which makes my job that much eaiser!). It is preserved in a neat pose that looks like it was buried in the mud, with just it's head exposed, while it awaited prey.This specimens come from the Belen formation [...]

Simon Gascoin captured this image of the badlands of the Palca canyon. The Palca canyon is located near the city of La Paz, Bolivia. Like much of the geology in the vicinity of La Paz, the canyon comprises mainly unconsolidated glacial formations, which are highly susceptible to wind and water erosion. The imposing spires, which

In the last few years there have been some interesting Devonian aged fossils coming out of Bolivia. I have mostly been purchasing mine from this seller on E-bay. They are found in small, round concretions so you often get a mold and cast of the fossil. Among the fossils I have acquired are some fairly nice trilobites with the most common specimens labelled Eldredgeia venustus; although some specimens could be another closely related genera, Metacryphaeus. The only way to tell them apart is to [...]

Among the fossils I have acquired are some unnamed crinoids.This is the third (and possibly fourth?) species that I have in my collection from Bolivia.This species has long arms covered in hair like pinnules that act like cilia to catch passing particles of food. Not much of the calyx has been preserved on this specimen so I don't have [...]

“Bolivia is a pretty dry place. [..] The slow decline of the glaciers there is a concern because these storehouses of ice supply about 20 percent of the water used by major Bolivian cities such as La Paz and Santa Cruz.” Quoted from the University Corporation for Atmospheric Research

La hiena gigante extinta Pachycrocuta brevirostris se trata de una especie de hiena de gran tamaño que se encuentra en el Pleistoceno inferior de la Península Ibérica. Su tamaño corporal sería el doble (unos 110 kilos) de las actuales hienas manchadas actuales como ha puesto de manifiesto un trabajo publicado en la revista Quaternary International y que ha sido liderado por los profesores Paul Palmqvist (catedrático del Departamento de Ecología y Geología de la Universidad de Málaga) [...]

Nach wochenlangen heftigen Regenfällen war der Boden in la Paz, Bolivien, mit Wasser gesättigt. Zusammen mit dem Relief hatte das in ganz Bolivien zu Überflutungen und Erdrutschen geführt. In der Hauptstadt, la Paz, war es zum Glück ein langsamer Erdrutsch, der allerdings ziemlich groß war und um die 400 Häuser zerstört hat. Hier finden sich einige beeindruckende Fotos dieses Ereignisses,welche die Dimension dieses Erdrutsches erahnen lassen. [...]
