Taphonomic Variability of Fossil Insects: A Biostratinomic Study of Palaeontinidae and Tettigarctidae (Insecta: Hemiptera) From the Jurassic Daohugou Lagerstatte

Abstract

A comprehensive, but simple-to-use software package for executing a range of standard numerical analysis and operations used in quantitative paleontology has been developed. The program, called PAST (PAleontological STatistics), runs on standard Windows computers and is available free of charge. PAST integrates spreadsheet-type data entry with univariate and multivariate statistics, curve fitting, timeseries analysis, data plotting, and simple phylogenetic analysis. Many of the functions are specific to paleontology and ecology, and these functions are not found in standard, more extensive, statistical packages. PAST also includes fourteen case studies (data files and exercises) illustrating use of the program for paleontological problems, making it a complete educational package for courses in quantitative methods.

New data on Jurassic Sinoalidae from northeastern China (Insecta, Hemiptera)

“…1;Wang, 2009). Daohugou is now considered to be one of the most important insect Lagerstätten (Rasnitsyn et al, 2006) and has yielded abundant and diverse insects (e.g., Wang and Zhang, 2011;B. Wang et al, 2013;Chen et al, 2014;Yan et al, 2014).…”

Taphonomic biases in the insect fossil record: shifts in articulation over geologic time

“…There tends to be a bias against large-winged or fragile groups such as Lepidoptera and against insects with wingspans smaller than 5 mm, typically leading to enrichment in heavy, medium-sized insects at the sediment interface relative to their life abundance. Archibald and Makarkin (2006) and Wang et al (2013) showed that insects with larger SM indices are more prone to disarticulation, likely due to longer floating time at the water surface. Larger wings commonly have microstructures that influence the wettability of the wings and can increase floating time as well (Wagner et al 1996;Rust 1998;Archibald and Makarkin 2006).…”

A new genus and species of Tettigarctidae from the Mesozoic of northeastern China (Insecta, Hemiptera, Cicadoidea)

“…The taxonomy of the Tettigarctidae is based mainly on the fore- and hindwing venation (Shcherbakov 2009, Li et al 2012), and this family is divided into two subfamilies based on forewing features: Cicadoprosbolinae Evans, 1956 and Tettigarctinae Distant, 1905 (Wang B and Zhang 2009, Li et al 2012). The fossils records of the Mesozoic Tettigarctidae are rather diverse (Nel 1996, Nel et al 1998, Dietrich 2002, Menon 2005, Moulds 2005, Wang B and Zhang 2009, Wang B et al 2013). The earliest Tettigarctidae appeared in the earliest Jurassic and terminal Triassic (ca.…”

“…A large number of fossils, especially the highly diverse array of insects, have been well-known and described from Daohugou based on the exceptionally well-preserved materials, showing sharp details of morphology, taxonomy and evolution (Rasnitsyn et al 2006, Pott et al 2012, Wang B et al 2013, Chen et al 2014, Wang H et al 2015). To date, 25 insect orders have been reported from the Daohugou Biota (Huang 2010, Li et al 2010, 2013, Wang B et al 2013).…”

“…To date, 25 insect orders have been reported from the Daohugou Biota (Huang 2010, Li et al 2010, 2013, Wang B et al 2013). In Tettigarctidae, eleven species within seven genera had been described from Daohugou to date (Wang B and Zhang 2009, Li et al 2012, Chen et al 2014, Chen et al 2016, Chen and Wang B 2016, this study).…”
