End of an Era

"What about?" I asked.

"Mars," said Diamond-snout. I looked into its huge yellow eyes with their rippling irises, almost hypnotically beautiful. "I ask you again about Mars of the future."

I shook my head, breaking away from the gaze. "And I tell you again: I’ve never been there."

Diamond-snout seemed unconvinced. "But if you ply time, doubtless you also ply space. And even if you donut" — a one-two blink — "do not, you must have magnifying optical devices that allow you to tell much about our home."

I looked at Klicks. He shrugged. "What you say is true, of course," I offered. "But without knowing what Mars is like currently here in the Mesozoic, we can’t very well describe how it differs, if at all, in our time. Surely you can understand that."

"Stop calling me Shirley," said Diamond-snout. It used my voice; it used my jokes. "Doubtless you can give us a thumb-claw sketch of Mars without us wasting time describing its current state. Do so."

"All right, dammit," I said. "You might as well know, anyway." I looked at Klicks once again, giving him a final chance to stop me if he thought I was making a huge mistake. His face was impassive. "I was telling the truth," I said, looking back into Diamond-snout’s golden orbs. "No human being has yet been to Mars — but we’ve sent some robot explorers there. They found a lot of weird chemistry in the soil, but no life." I looked at Diamond-snout. Its head had dipped low, the golden orbs with their vertical, cat-like pupils staring at the cracked mud. It was madness to try to interpret its expressions, to try to apply human emotions to a glob of jelly and its dinosaur marionette, and yet, to me, the thing looked shaken. "I’m terribly sorry," I said.

"Mars dead," said the troodon, looking up again, the reflections of the afternoon sun like little novas in its glistening eyes. "Confirm that that is your meaning."

"I’m afraid it’s true," I said, surprised at the emotion in my own voice. "Mars is indeed dead." The beast’s muscles went limp as the Het within presumably tried to digest this information. My heart went out to the being. And yet, on the other hand, if a time traveler were to arrive in 2013 from 65 million years in the future, I’d fully expect him to say that my kind had passed from the face of the Earth, too. "Look," I said softly. "It’s not so bad. We’re talking about an inconceivably long time from now."

The troodon fixed me with a steady gaze. It reminded me of Klicks’s how-dense-can-you-be look. "As said we before, our history goes back almost double that length of time. For us, it is not inconceivably distant." Again it dipped its long face, looking at the dried mud’s pattern of cracks and curled edges. "You speak of our extinction."

Klicks smiled reassuringly. "All lifeforms die out eventually," he said. "It’s the nature of things. Take the dinosaurs—"

"Klicks…"

"They’ve also been around for over a hundred million years and sometime very soon they’re going to be wiped out."

Diamond-snout’s head snapped up. The golden eyes locked on Klicks. "What?"

It was too late to stop him. "It’s true, I’m afraid," Klicks continued. "Earth’s ecosystem is about to change and the dinosaurs won’t be able to hack it."

"Soon," said Diamond-snout, the single word sounding like a hiss. "You say soon. How soon?"

"Very soon," Klicks said. "I don’t mean any day now, of course." He grinned. "But we were aiming for the point in geologic history at which the last dinosaur fossils were found. Our time-travel technology has a fundamental, unavoidable uncertainty about it. The end of the dinosaurs could be as much as three hundred thousand years in the future. Or it could be much, much sooner."

"What is planet five like?" Diamond-snout asked suddenly.

"Planet five?" I said, lost.

The yellow orbs swung on me. "Yess, yess," the thing hissed. "Fifth planet from sun."

"Oh, Jupiter," I said. "In our time, it’s pretty much the same as we think it always has been: a gas giant, a failed star." I scratched my ear. "It’s got a nice little ring now, though, which might not have existed in this time. Nothing like Saturn’s, of course, but still pretty neat."

"Jupiter … oh, see I do," said the Het. "And between Mars and Jupiter?"

"The asteroid belt, of course."

"Of course," said Diamond-snout quickly. The three troodons looked at each other, then turned, their stiff tails swishing through the air; Klicks and I had to step back to avoid being whipped by them. In unison they began to march away.

"Wait a minute," called Klicks. "Where are you going?"

Diamond-snout swiveled its pointed head back at us for a moment, but the troodons didn’t stop striding away. Giant yellow eyes closed and opened in turns as it rasped, "To attend to our hygiene."
