Biostratigraphy.com, LLC is a Dallas-based consulting company, formed after the BPAmoco-Arco merger, that provides big company biostratigraphy services to any size company. Through an extensive worldwide network of affiliated experts, we can select the best expert, or team of experts, to meet your needs. Affiliates include paleontological experts from around the world: Houston, Dallas, Alaska, Florida, Canada, Trinidad, Venezuela, UK, France, Indonesia and more.

Custom software and databases, developed over the last 25 years, allow 3 to 5 times higher age resolution than normal for data collected to our specifications. One database has over one million age citations for fossil occurrences.

Re-studying existing biostratigraphic data sets with these tools often yields 2 to 3 times higher age resolution.

Depositional systems (paleoenvironments) are interpreted within age constrained intervals. For Tertiary age sediments, depositional systems are defined using transfer functions from modern analogs; for the pre-Tertiary, multivariate analyses (PCA, factor and cluster analyses) are used to extract environmental groupings that define depositional systems.

We have successfully applied these methods to exploration around the world, especially in West Africa. We have integrated and interpreted stratigraphic data extensively in: Alaska, Algeria, Angola, Morocco, East Africa (Kenya and Mozambique), West Africa (Gabon, Ghana, Cameroon and Equatorial Guinea), Bolivia, Colombia, China (Songliao Basin, South China Sea), CIS (Sakhalin Island), Ecuador, Mexico, Suriname and Guyana, Indonesia (Irian Jaya), Kazakhstan, Korea, Myanmar, Peru, Philippines (Sulu Sea), Oman, Papua New Guinea, Thailand, Trinidad, Tunisia, Turkey (Black Sea), Venezuela, and Vietnam.

Comparisons:
Some of the biggest differences between Biostratigraphy.com, LLC and the large integrated consulting companies:

Our analysts are selected from the best available experts (worldwide), rather than a limited in-house staff.

There is less overhead and infrastructure to support, so more funds are directed to our analysts for higher quality data collection.

Our analysts are sub-contractors whose results are monitored and quality controlled by Biostratigraphy.com, LLC.

All analyses are performed independently. There is no communication between analysts until after the data collection phase is complete.

Multidiscipline studies benefit from multiple expert opinions. Each analyst offers their independent interpretation.

Interactive, iterative analysis of fossil occurrence data and age significance results in "cleaner" in-situ data and identification of valuable reworking events.

All fossils with age citations are used to define an age / depth profile, rather than only "index" fossils. Resulting age/depth charts define age intervals, rates of deposition, and placement and duration of unconformities.
