Plant Fossils Across Continental Boundaries
Evidence for a Pre-Flood Supercontinent and the Destruction of Ecosystems in the Global Flood
Introduction
Genesis 1:9–10 records that God gathered the waters into one place so that the dry land appeared. From Creation Week until the Flood, that single landmass of sialic cratons existed as one unified supercontinent. The fossil record is not the product of gradual processes over deep time. It is the direct result of the destruction of pre-Flood ecosystems during the global Flood of Noah’s day. Plant fossils provide particularly clear evidence of this history because their distributions match across what are now separated continental boundaries, demonstrating that those boundaries did not exist when the ecosystems were destroyed and the sediments were deposited.
This paper analyzes the worldwide distribution of plant fossils, with particular emphasis on similarities across continental boundaries. It demonstrates that lower (earliest Flood) layers preserve floral assemblages consistent with burial on a single landmass, while higher layers reflect progressive continental separation during the Flood. The analysis draws on the geological and paleontological evidence presented in our prior work, and aligns with the Catastrophic Plate Tectonics model. Particular attention is given to Glossopteris, the Euramerican coal flora, polystrate fossils, and the relationship between plant assemblages and the megasequence framework of the Flood.
The Pre-Flood Supercontinent and Catastrophic Plate Tectonics
As documented in “The Craton Record,” our reconstructions place a slightly modified Pangaea configuration centered near the equator as the best empirical fit for the pre-Flood supercontinent. This configuration is confirmed by precise fits of ancient cratons, matching rock types, paleomagnetic data, and a continuous belt of thick Late Precambrian salt deposits that only form a coherent unit when the continents are restored to this layout (Wright, 2026a). The Laurentian craton (the ancient heart of North America) fitted snugly against the West African craton and the Amazonian craton. South America’s Amazonian and São Francisco cratons locked against Africa’s Congo and Kaapvaal cratons along the Gulf of Guinea. In the southern hemisphere, Australia’s Pilbara and Yilgarn cratons connected via East Antarctica’s Mawson craton to India’s cratons and Africa’s Kalahari structures. These fits perfectly match rock types, Glossopteris and Mesosaurus fossils, and paleomagnetic data.
The continuous belt of evaporite salts, thousands of feet thick in the Persian Gulf (Hormuz Evaporites), Pakistan (Salt Range Formation), and western India (Hanseran Evaporites), only forms a coherent geologic unit when the continents are restored in this Pangaea-like pre-Flood layout. This craton-premised evidence powerfully confirms that a single landmass existed before the Flood began. Scripture aligns perfectly with this evidence. Genesis 1:9–10 records God commanding the waters to gather into one place so dry land appeared, describing the pre-Flood supercontinent of sialic cratons that existed from Creation Week until the Flood onset.
On the seventeenth day of the second month in Noah’s six hundredth year, “all the fountains of the great deep were broken up” (Genesis 7:11). That rupture initiated Catastrophic Plate Tectonics. Pre-Flood oceanic lithosphere began runaway subduction. Continents raced apart in months, not millions of years. A short-lived intermediate supercontinent formed during the first 150 days of the Flood. By the end of the Flood year the fountains were stopped, the waters receded, and the landmasses stood in essentially their present positions (Wright, 2026b). The plant fossil record records the destruction of ecosystems that existed on this single landmass before and during the early stages of separation. Giant tsunamis laid uniform megasequences separated by continent-wide unconformities across craton platforms, while chaotic edge deposits formed around the stable craton cores from underwater collisions during the Flood’s peak.
Glossopteris and the Southern Continents
Glossopteris, the distinctive seed-fern whose tongue-shaped leaves dominate many southern Permian deposits, is found across South America, Africa, India, Australia, and Antarctica. Its large seeds could not have floated or blown across the present oceans. When those continents are restored to the pre-Flood configuration, the Glossopteris fossils form a continuous belt across what was the southern portion of the single landmass. The same holds for the associated coal measures that contain them. These plants grew in pre-Flood southern ecosystems. When the Flood waters destroyed those ecosystems, the plant debris was buried in sediments that were still on the connected (or newly separating) crustal pieces. As Catastrophic Plate Tectonics carried the pieces apart, the fossil-bearing layers went with them.
This distribution is not the result of gradual evolution across deep time. It is the rapid burial of one connected flora on a single landmass that was subsequently divided. The same pattern of matching fossils across restored continental boundaries appears with the reptile Mesosaurus, reinforcing the plant evidence. Glossopteris forests contributed heavily to the vast Permian coal deposits of the southern continents. These coals display the same features of rapid burial and marine mixing seen in northern coal measures, confirming that both were produced by the same global event rather than by long-lived, geographically isolated swamp environments.
The presence of Glossopteris in what are now polar regions is readily explained by the equatorial-centered pre-Flood configuration. Southern Patagonia and Antarctica were not polar outposts for tens of millions of years. They belonged to the original equatorial landmass and were carried to higher latitudes by the rapid tectonics of the Flood year itself.
The Euramerican Coal Flora and Floating Log Mats
The same pattern appears in the great Carboniferous coal measures. Lepidodendron (the scale trees), Sigillaria, Calamites (giant horsetails), Neuropteris and Pecopteris seed-ferns, Cordaites, and the associated ferns dominate the coal seams of eastern North America, Europe, and parts of North Africa. These identical plant assemblages match across the present Atlantic boundary. In the pre-Flood supercontinent they occupied the equatorial and tropical zones of the single landmass. When the fountains of the great deep broke up and the surging waters sheared entire forests from their roots, the vegetation formed continent-scale floating log mats. Those mats were repeatedly driven onto the rising and falling sediments, producing the stacked, pure coal seams mined today.
As detailed in “Coal Formation and the Global Flood,” the volume of coal worldwide indicates 8–10 times more vegetation on the pre-Flood earth than exists today. That is exactly what Genesis 1:31 describes as a “very good” creation under ideal conditions (Wright, 2026c). Pre-Flood forests included lycopods, ferns, horsetails, and cycads that flourished under high-pressure, oxygen-rich atmospheric conditions with mist-watering. The 1980 Mount St. Helens eruption provides a modern analog: at Spirit Lake a massive log mat formed on the water’s surface. Bark was abraded, logs sank root-first, and the mats persisted long enough for successive surges to deposit stacked seams separated by sediment.
The dynamic floating log-mat model accounts for polystrate fossils (trees extending through multiple layers), flat-topped and flat-bottomed coal beds, and the remarkable purity of many seams (minimal soil or clay mixed in, unlike slow swamp accumulation). It also explains distinctive features such as partings, splits, cutouts, and rolls. Marine fossils (sharks, crinoids, brachiopods, tubeworms, goniatites) are frequently found intimately associated with terrestrial plant remains inside coal seams and coal balls. Examples include a fossil shark jaw recovered from a Kentucky coal mine and marine invertebrates in Pennsylvanian coal balls from the Illinois Basin and Midland Basin. These mixed assemblages demand catastrophic transport and mixing during Flood surges as log mats drifted on turbulent waters that transitioned from freshwater runoff to fully marine conditions.
Laboratory experiments show that lignin heated with clays such as montmorillonite at approximately 150 °C produces coal-like materials in weeks to months. Carbon-14 is detectable in coal, indicating formation thousands of years ago rather than hundreds of millions of years. These observations cohere with rapid coalification under the heat, pressure, and volcanic catalysts of the Flood year.
Stratigraphic Implications: Lower Versus Higher Layers
Flood geologists recognize that the sedimentary record of the continents is organized into a handful of continent-scale packages called megasequences. From oldest (early Flood) to youngest they are the Sauk, Tippecanoe, Kaskaskia, Absaroka, Zuni, and Tejas. Each records a major pulse of rising and then receding water as the Flood progressed. The earliest Flood layers (the lower megasequences) were laid down while the landmasses were still largely together or only beginning to separate. Those layers therefore preserve more broadly matching plant assemblages that reflect the connected ecosystems of the single continent.
Higher layers, deposited later in the Flood after the continents had moved farther apart, show greater differentiation. The plant debris was buried on the separating pieces of crust, so the fossils now appear more provincial. What secular geology calls distinct floral provinces (Euramerican, Gondwanan, Angaran, Cathaysian) are simply the pre-Flood ecological zones (latitude, elevation, and climate) on one continent, buried in sequence as the waters rose and the plates moved. Boundaries between these provinces grade into mixed assemblages precisely along the suture zones created by the rapid plate motions of the Flood.
Giant sequoia-type fossils appear worldwide, confirming that these magnificent trees once formed major components of pre-Flood forests across the single landmass. Their living descendants today, and the age of the oldest living specimens, fit the biblical timeline of roughly 4,500 years since the Flood. Polystrate fossils of both trees and other organisms further demonstrate that multiple sediment packages were deposited in rapid succession as successive ecosystems were inundated.
Discussion
Matching plant fossils across continental boundaries are not an anomaly. They are precisely what is expected when a single pre-Flood continent, covered by abundant, highly productive ecosystems, was destroyed by the global Flood and its pieces were carried apart by Catastrophic Plate Tectonics. The lower sediment packages record the early stages of that destruction while the land was still largely one. The higher packages record the later stages after the fountains of the great deep had driven the continents apart.
Secular paleobotany recognizes four classical Late Paleozoic floral provinces. The Euramerican coal-swamp flora dominated equatorial regions now found in eastern North America, Europe, and North Africa. The Gondwanan Glossopteris flora is restricted to the southern continents. The Angara flora occupied present-day Siberia, and the Cathaysian flora occupied East Asia. These provinces are characterized by distinct genera and species, yet their boundaries grade into mixed assemblages along plate-tectonic suture zones. In the Flood framework these provinces reflect pre-Flood ecological zonation on one continent rather than long isolation of separate landmasses. The matching of identical plant taxa across restored boundaries is the decisive evidence that those boundaries did not exist when the plants were growing and when the sediments that entombed them were laid down.
These plant fossils join the craton fits, the continuous salt belts, the marine-mixed coals, and the megasequence packages as consistent testimony that the fossil record is the burial ground of ecosystems destroyed in the year of Noah’s Flood. The same God who judged the world by water and preserved life through the Ark offers salvation today through Jesus Christ, the greater Ark. The rocks continue to speak of that real history.
Conclusion
The worldwide distribution of plant fossils, particularly the identical assemblages that match across restored continental boundaries, supports the interpretation that the fossil record resulted from the destruction of ecosystems during the global Flood. At the time the lower sediment layers were deposited, a single continent existed. Higher layers were deposited as Catastrophic Plate Tectonics separated the landmasses later in the Flood year. Glossopteris, the Euramerican coal flora, polystrate fossils, marine-mixed plant remains, and the megasequence framework all cohere with this biblical account. The evidence affirms the reliability of Genesis and points to the hope available in Christ.
