Ancient Vomit Reveals a Prehistoric Food Web – And Hints at Future Fossil Discoveries
A remarkably preserved fossilized regurgitalite – essentially, ancient vomit – unearthed in Germany is rewriting our understanding of life before the dinosaurs. This walnut-sized lump, dating back approximately 290 million years, contains the remains of three different animals, offering a rare snapshot of predator-prey relationships in the Early Permian period. But this discovery isn’t just a glimpse into the past; it signals exciting new avenues for paleontological research and how we interpret fossil records.
The Power of “Regurgitalites” – Beyond Bones
Traditionally, paleontologists reconstruct ancient ecosystems from scattered bones and teeth. However, these remains often lack the crucial context of how animals interacted. Fossilized vomit, or regurgitalites, provide that missing link. As described in a recent study published in Scientific Reports, this particular specimen offers a direct record of a meal, revealing which creatures were on the menu for early land predators.
Unlocking Dietary Secrets with Micro-CT Scanning
The team at the Museum für Naturkunde Berlin (MfN) employed micro-CT scanning to analyze the regurgitalite without damaging the delicate fossil. This high-resolution X-ray technique allowed them to digitally separate the bones from the surrounding sandstone, identifying fragments from Thuringothyris mahlendorffae and Eudibamus cursoris. The use of non-destructive imaging is becoming increasingly common in paleontology, allowing for detailed analysis without compromising precious specimens.
Chemical Clues and the Distinction from Coprolites
Distinguishing between regurgitalites and coprolites (fossilized feces) is crucial for accurate interpretation. Researchers utilized chemical analysis, specifically examining phosphorus levels. Regurgitalites typically exhibit lower phosphorus concentrations in the surrounding sediment compared to coprolites, supporting the identification of this specimen as stomach contents expelled before complete digestion. This highlights the growing role of geochemical analysis in paleontological investigations.
Implications for Understanding Early Land Ecosystems
The presence of multiple prey species within a single regurgitalite suggests opportunistic feeding behavior. The predator likely consumed whatever was readily available, rather than focusing on a single type of prey. The potential culprits, Dimetrodon teutonis and Tambacarnifex unguifalcatus, were both synapsids – ancestors of mammals – and apex predators in the Bromacker ecosystem. This discovery reinforces the idea that early terrestrial food webs were complex and dynamic.
Bromacker: A Unique Fossil Hotspot
The Bromacker locality in Thuringia, Germany, is exceptional for its well-preserved land skeletons, trackways, and now, regurgitalites. The site’s unique geological conditions – rapid burial in fine-grained sediments – have allowed for the preservation of delicate fossils and behavioral evidence that are rarely found elsewhere. The long-running excavation efforts at Bromacker, initiated in 1974, continue to yield invaluable insights into the Permian period.
Future Trends in Paleontological Research
The Bromacker regurgitalite is a harbinger of future trends in paleontology. We can expect to see:
Increased Use of Non-Destructive Imaging
Micro-CT scanning and other non-destructive techniques will become standard practice, allowing researchers to analyze fossils in unprecedented detail without risking damage. This will unlock new information from existing museum collections and accelerate the pace of discovery.
Integration of Chemical and Geological Data
Combining paleontological data with geochemical and geological analyses will provide a more holistic understanding of ancient ecosystems. Analyzing sediment composition, stable isotopes, and trace elements can reveal information about climate, diet, and environmental conditions.
Focus on Behavioral Paleontology
The study of fossilized behaviors – such as feeding, locomotion, and social interactions – will gain prominence. Trackways, burrows, and now regurgitalites offer direct evidence of how ancient animals lived and interacted with their environment.
Expanding the Search for Regurgitalites
Paleontologists will actively search for more regurgitalites in other fossil-rich localities. These rare finds have the potential to revolutionize our understanding of ancient food webs and predator-prey relationships.
FAQ
Q: What is a regurgitalite?

A: They provide direct evidence of what ancient animals ate, offering insights into predator-prey relationships and food web dynamics.
Q: Where was this regurgitalite found?
A: It was discovered at the Bromacker locality in Thuringia, Germany.
Q: What animals were identified in the regurgitalite?
A: Remains of Thuringothyris mahlendorffae and Eudibamus cursoris were found.
Q: What does this discovery share us about the predators of the time?
A: It suggests that predators like Dimetrodon teutonis and Tambacarnifex unguifalcatus were opportunistic feeders.
Did you grasp? The Bromacker locality is known for its exceptional preservation of Permian-era fossils, offering a unique window into life before the dinosaurs.
