What main characteristic distinguishes the fossil record of the Paleozoic Era from that of the Precambrian Era?
The main characteristic that distinguishes the fossil record of the Paleozoic Era from the Precambrian Era is the appearance of diverse and complex multicellular organisms in the Paleozoic Era. In the Precambrian Era, the fossil record primarily consists of simpler single-celled organisms. Additionally, the Cambrian Explosion, which occurred at the beginning of the Paleozoic Era, marked a significant increase in the diversity of life forms.
When does the fossil record indicate when birds first began to fly?
The fossil record suggests that the earliest known bird capable of powered flight was Archaeopteryx, which lived around 150 million years ago during the late Jurassic period. This indicates that birds began to fly during the Mesozoic Era.
How long ago did The Paleozoic era began?
The Paleozoic era began about 543 million years ago. It came after the Precambrian era and before the Mesozoic era.
Abundant fossil evidence did not appear in the geologic record until what geologic era?
Abundant and diverse fossils first appeared in the Cambrian era, although there is fossil evidence throughout much of the Precambrian.
What is the chronological collection of life's remains found in layers of rock?
The answer is the fossil record :D
The most complete fossil record of past invertebrate life in NJ can be found in rocks of with era?
paleozoic
Which era did people evolve in?
Humans evolved in the Pleistocene era, which is the most recent part of the larger Cenozoic era. Modern humans first begin appearing in the fossil record approximately 200,000 years ago.
How does the fossil record organize fossil?
The fossil record organizes fos- sils by their estimated ages and physical similarities.
How are fossil organized in the fossil record?
The fossil record organizes fos- sils by their estimated ages and physical similarities.
What era is know as the age of invertebrates?
The age of invertebrates is primarily known as the Paleozoic Era, particularly during the Cambrian period, which began around 541 million years ago. This era saw a significant explosion of marine life, with invertebrates such as trilobites, mollusks, and echinoderms becoming dominant. The fossil record from this time showcases a diverse array of invertebrate species that played crucial roles in early ecosystems.
How did the coming of the Europeans to North America bring an end to the prehistoric era?
The Europeans began to record information about the Native Americans in their journals.
What is the age of the oldest fossil on record?
The age of the oldest fossil on record is about 3.5 billion years old.
