Question

zygodactylus was an ancient animal that lived about 52,000,000 years ago. here are pictures of a zygodactylus fossil, a living chicken, and a living green basilisk. which traits can you observe in the fossil of zygodactylus, the living chicken, and the living green basilisk? complete the table. based on the table, which living animal shares more traits with zygodactylus? chicken green basilisk

Explanation:

• A beak: Chickens have beaks. From the fossil, Zygodactylus also seems to have a beak - like structure. Green basilisks have mouths with teeth (not a beak).
• Toes on its feet: All three - Zygodactylus (from the fossil structure of feet), chicken, and green basilisk have toes on their feet.
• Walks on two legs: Chickens are bipedal. From the fossil structure (upright posture with two legs supporting the body), Zygodactylus likely walked on two legs. Green basilisks can run on two legs for short distances but also use four legs; but in terms of a more typical trait, we can consider the fossil and chicken more clearly show this trait.
• A long tail: From the fossil, Zygodactylus has a long tail. Green basilisks have long tails. Chickens have relatively short tails compared to these two.

Answer:

Trait	Zygodactylus	Chicken	Green basilisk
Forelimb wings that fold against its body	✓	✓
Toes on its feet	✓	✓	✓
Walks on two legs	✓	✓
A long tail	✓		✓

Based on the table, the chicken shares more traits (4 traits: beak, forelimb wings that fold against the body, toes on feet, walks on two legs) with Zygodactylus compared to the green basilisk (2 traits: toes on feet, long tail). So the answer is chicken.
