The oldest fossil evidence of seed plants dates back to the late Devonian period, approximately 360 million years ago. These earliest fossils include primitive seeds found in ancient soils and reproductive structures resembling modern-day seed ferns.
Response to the query in detail
The oldest fossil evidence of seed plants can be traced back to the late Devonian period, approximately 360 million years ago. This remarkable discovery sheds light on the early evolution of plants and their reproductive strategies. Fossils from this period reveal the existence of primitive seeds and reproductive structures resembling modern-day seed ferns. This pivotal development in the history of plants marked the transition from primitive spore-bearing plants to more advanced seed-bearing plants.
Interestingly, this significant milestone in plant evolution has captivated the attention of scientists and researchers worldwide. Let’s delve deeper into the topic by exploring some fascinating facts and a quote from a renowned expert:
-
The late Devonian period, also known as the “Age of Fishes,” witnessed a tremendous diversification in plant life, with seed plants emerging as major players in terrestrial ecosystems.
-
The development of seeds revolutionized plant reproduction by enabling the propagation of offspring with built-in food reserves and protective coatings.
-
The fossilized seeds from this period often exhibit a protective outer covering to safeguard the developing embryo, indicating an adaptation for survival in varied environments.
-
Seed ferns, the ancient plants closely resembling the reproductive structures found during this period, were not true ferns but rather a unique group of plants with fern-like leaves and seed-like structures.
-
The discovery of these ancient seed plants highlights the remarkable resilience and adaptability of early terrestrial plants in the face of changing environmental conditions.
As plant paleontologist Dr. James A. Doyle eloquently stated, “Seeds allowed plants to cope with new types of habitats. They could disperse and survive in a dormant state, only germinating when conditions were optimal. It was truly an evolutionary turning point.”
Table:
| Period | Age (in million years) | Key Discovery |
|---|---|---|
| Late Devonian | Approximately 360 | Oldest fossil evidence of seed plants |
In conclusion, the oldest fossil evidence of seed plants dates back to the late Devonian period, providing a window into the fascinating evolutionary journey of plants. This pivotal development marked the emergence of seed plants and their subsequent domination of terrestrial ecosystems.
Answer in video
This video explores the evolution of early plants and their diverse characteristics. It delves into the Ordovician and Silurian periods, where microscopic spores suggest the colonization of land by plants. The video also highlights the emergence of plant fossils like Cooksonia in the Silurian period and the role of resistant walled spores in dispersal. The Devonian period saw the rapid development and diversification of land plants, with the appearance of various species like rhyniophytes and cyclophytes. The Rhynie Chert fossil occurrence in Scotland provides valuable insights into the structure of early land plants. As plants continued to evolve, conducting cells became vital for water supply and internal support, leading to the development of woody tissue and the appearance of the earliest true trees. The video also mentions other intriguing fossils like Prototaxites and Parka, as well as the unique features and adaptations of early plants. It concludes with the evolution of plants like Monarodendron, Steroxylon machiae, Asteroxylon, and Archeopterius, showcasing the range of sizes and growth forms in this early period of plant evolution.
There are several ways to resolve your query
Gymnosperms were the first seed plants to have evolved. The earliest seedlike bodies are found in rocks of the Upper Devonian Series (about 382.7 million to 358.9 million years ago).
Elkinsia polymorpha
The oldest known seed plant is Elkinsia polymorpha, a "seed fern" from Late Devonian (Famennian) of West Virginia. Though the fossils consist only of small seed-bearing shoots, these fragments are quite well-preserved.
The earliest seeds appear in the Late Devonian. The oldest known seed plant is Elkinsia polymorpha, a "seed fern" from Late Devonian (Famennian) of West Virginia. Though the fossils consist only of small seed-bearing shoots, these fragments are quite well-preserved.
The oldest fossil evidence of seed plants is of Late Devonian age, and they appear to have evolved out of an earlier group known as the progymnosperms. These early seed plants ranged from trees to small, rambling shrubs; like most early progymnosperms, they were woody plants with fern-like foliage.

One may also ask, What is the first seed plant fossil? Answer will be: plant Elkinsia polymorpha
The fossil plant Elkinsia polymorpha, a “seed fern” from the Devonian period—about 400 million years ago—is considered the earliest seed plant known to date.
What is the oldest fossil record of plants?
WASHINGTON (Reuters) – Scientists have spotted in rocks from northern China what may be the oldest fossils of a green plant ever found, tiny seaweed that carpeted areas of the seafloor roughly a billion years ago and were part of a primordial revolution among life on Earth.
Also asked, Where were the earliest known seed plant fossils found?
The earliest seeds appear in the Late Devonian.
The oldest known seed plant is Elkinsia polymorpha, a "seed fern" from Late Devonian (Famennian) of West Virginia. Though the fossils consist only of small seed-bearing shoots, these fragments are quite well-preserved.
Considering this, When did the first seed plants appear on Earth?
Plants are thought to have made the leap from the oceans onto dry land about 450 million years ago. And, as seeds are thought to have developed to keep plant embryos from drying out, it makes sense that the first seeds we know of are at least 360 million years old.
Keeping this in consideration, What is the earliest fossil evidence for land plants?
The reply will be: The earliest fossil evidence for land plants comes from microscopic dispersed spores 1, 2, 3. These microfossils are abundant and widely distributed in sediments, and the earliest generally accepted reports are from rocks of mid-Ordovician age (Llanvirn, 475 million years ago) 4.
Subsequently, When did seeds first appear on Earth?
In reply to that: The earliest seeds appear in the Late Devonian. The oldest known seed plant is Elkinsia polymorpha, a "seed fern" from Late Devonian (Famennian) of West Virginia. Though the fossils consist only of small seed-bearing shoots, these fragments are quite well-preserved.

What is the oldest plant-like fossil ever discovered? They looked “fleshy,” even. These fossils, as Sallstedt and her colleagues report in PLOS ONE, appear to be 1.6-billion-year-old red algae. That makes them the oldest plant-like fossils ever discovered; the previous oldest algae was 1.2 billion years old. It was, for Sallstedt, an amazing find.
