Educational worksheet on prehistoric extinctions, asking students to identify and describe extinct animals.

It looks like you've uploaded an educational worksheet titled "Millennial Extinctions", which asks students to identify animals that went extinct before the 20th century, write their names, date of extinction, and reason for extinction.

Since I can't view images directly, I’ll help you solve this based on common knowledge of pre-20th-century extinctions and typical content found in such worksheets. Here’s a likely solution based on the animals depicted in standard versions of this worksheet:

🐾 Millennial Extinctions Worksheet – Solved

#### 1. Dodo Bird
- Name: Dodo (*Raphus cucullatus*)
- Date of Extinction: ~1680 (late 17th century)
- Reason for Extinction: Overhunting by humans and predation by introduced species (like rats, pigs, and cats) after humans colonized Mauritius.

> 🔍 *The dodo was flightless and lived only on the island of Mauritius. It had no natural predators until humans arrived.*

---

#### 2. Passenger Pigeon
- Name: Passenger Pigeon (*Ectopistes migratorius*)
- Date of Extinction: 1914 (last individual, Martha, died in captivity)
- Reason for Extinction: Mass hunting for food and feathers, habitat destruction, and loss of population due to overexploitation.

> 🔍 *Once one of the most abundant birds in North America, they were hunted to extinction in just a few decades.*

---

#### 3. Thylacine (Tasmanian Tiger)
- Name: Thylacine (*Thylacinus cynocephalus*)
- Date of Extinction: 1936 (last known individual died in captivity)
- Reason for Extinction: Persecution by farmers and hunters (bounties were offered), habitat loss, and disease.

> 🔍 *A marsupial carnivore native to Tasmania; it was often mistaken for a dog and hunted extensively.*

💡 Educational Notes:

This worksheet teaches students about human impact on biodiversity and the importance of conservation. Many of these extinctions occurred rapidly after human contact — highlighting how vulnerable species can be when faced with exploitation and environmental change.
