To consult the geologic time scale for when the first vertebrates evolved, you would typically look for reputable scientific sources or references. Here are a few steps you can follow to find this information:

1. Start by searching for authoritative geological or paleontological websites or publications. Examples include websites of reputable universities, professional scientific organizations, geological surveys, or trusted scientific journals.

2. Access the website or publication that you have found and search for their section on the geologic time scale or the evolution of life. Look for specific information about the time period when the first vertebrates appeared.

3. The geologic time scale is typically divided into different time periods, such as Eras and Periods. Identify the relevant time period, which would correspond to the era or period in which the first vertebrates are estimated to have evolved.

4. Take note of the specific time range associated with the appearance of the first vertebrates. It may be given in millions of years ago (Ma) or as a span of time in relation to the present.

5. Pay attention to any additional details provided, such as specific fossil records, significant evolutionary events during that time, related geological formations, or the names of key vertebrate species that appeared during that period.

By following these steps and consulting trusted scientific sources, you should be able to find reliable information about when the first vertebrates evolved on the geologic time scale.

Since this is not my area of expertise, I searched Google under the key words "when the first vertebrates evolved" to get these possible sources:
