Wham!

The Sternberger shook under a tremendous impact, the hull reverberating, the sound of water in the partially empty tank beneath our feet slapping in a giant wave against one side of the timeship. I staggered, trying to keep my balance. Through the glassteel over the radio console, I could see something dark and gray, like a flying wall, pulling back, farther and farther, bits of sky now visible above it, the brown of the mud plain starting to peek out below it, the gray wall retracting more and more…

A tail. A dinosaur tail. The part that had connected with the timeship was almost twice as high as a man. The tail was flattened from side to side, a giant tapering structure covered with wrinkled gray leather. It was still pulling back and back, until finally the creature it belonged to was fully visible.

A sauropod, a member of that giant quadrupedal group typified by what most people still called Brontosaurus, standing out there on the mud plain, perpendicular to the crater wall, its elongated tail balanced by a similarly long neck rising up and up into the sky, ending in a tiny block-shaped head. In between neck and tail, a vast gray torso like the Goodyear blimp supported by massive column-like legs…

Sauropods were rare in the Upper Cretaceous, and none had ever been found in Alberta — too wet for them, according to one school of thought. Still, at this time there was Alamosaurus in New Mexico, Antarctosaurus, Argyrosaurus, Laplatasaurus, Neuquensaurus, and Titanosaurus in Argentina, and a handful of others in China, Hungary, India, and elsewhere. I supposed that if the Hets needed a living crane, flying one in presented no problem for them. Although they’d been nicknamed thunder lizards, sauropods had massively padded feet. This one, despite its size, had obviously had no trouble sneaking up on us.

The tail had finished pulling back and now was reversing its course, slicing through the air toward us, zooming in to dominate the view out the window -

The first impact clearly had been just a warm-up. Klicks and I went flying when the tail connected with full force. He landed in a heap by his crash couch; I ended up smashing into the washroom door panel. I tried to rise to my feet and looked over at Klicks, who was bracing himself against the fake wood-grain molding around the edges of the radio console. His eyes were closed as he listened to that inner voice once more. "They’re going to take our timeship one way or another," he said.

A third impact by the sauropod tail again knocked Klicks and me to the floor, something neither of us was in any condition to endure. I put my hand to my face and it came away wet. My nose had started bleeding again. Two more blows from the giant’s tail dislodged the Sternberger from its perch atop the crater wall. I’d thought it had been bad going down that slope in the Jeep, but at least I’d been strapped in and had had the benefits of the vehicle’s shock absorbers. This time, loose pieces of equipment flew around the cabin as our timeship skidded down the crumbling earth. Klicks and I were tossed like rag dolls in a clothes dryer, bruising elbows, banging knees, twisting limbs. The Sternberger finally, mercifully, came to a stop on the mud flat, tilted at a bit of an angle. We staggered to the window.

Dinosaurs were moving in from every direction. A dozen dark red juvenile tyrannosaurs clustered along the shore of the lake, their bird-like feet giving them excellent traction in the mud. Seven triceratops tanks, garish in their blue and orange camouflage, lumbered in to form an arc to the southwest, heads bent low so that their mighty eye horns stuck straight out. Next to them stood the gargantuan gray sauropod with its skyscraper neck and a tail that seemed to go on forever. Thirty or so troodons milled about, hopping from foot to foot, their stiff tails bouncing up and down like conductors’ batons. Goose-stepping in from the west were five giant adult females of the species Tyrannosaurus rex.

Standing behind the others, one duckbill reared up on its hind legs. It was a member of the genus Parasaurolophus, just like the famous specimen we had at the ROM, a meter-long tubular crest extending back from its skull. At first I couldn’t fathom what that cow-like reptile was doing here. I’d imagined the Hets simply raised duckbills in herds to feed the fighting carnivores. But then the hadrosaur let out a series of great reverberating notes, its crest acting like a resonating chamber. The tyrannosaurs dispersed and I realized that the duckbill was calling out the orders of the Het general riding within it, the hadrosaur’s thunderous voice carrying for kilometers.

I looked at our Jeep, over by the western base of the crater wall. The two tires I could see from this angle were completely flat — pierced open, I suspected, by triceratops horns.

A troodon stepped up to the window that Klicks and I were looking through. It stood on tippy-toe to see in, its pointed muzzle just coming to the bottom of the glassteel. The beast regarded us for a few seconds, gave its weird one-two blink, and then spoke, its raspy voice audible through the air vents around our roof. "Come out now," it said. "Surrender the time-ship. Do these things or die."

The maximum a siege could last would be twenty-two hours; after that, the Sternberger was going home regardless. We could comfortably wait that long since we had plenty of food and water. But it seemed pretty clear that the Hets weren’t just going to hang around outside until the Huang Effect reversed states. They intended to be on board when that happened, bypassing their own extinction.

Klicks ran to get our elephant guns but he shook his head as he passed one to me. "We could pump every bullet we’ve got into that sauropod and probably not even slow it down."

From outside, the troodon’s gravelly voice shouted: "Last warning. Out now."

Klicks grabbed the red tool chest he had heaved through the air earlier and stood upon it, its sheet-metal construction caving in a bit under his weight. He jammed the butt of his rifle into the wire mesh that covered one of the air vents at the top of the curving outer wall, clearing the mesh away. Then he turned the weapon around and pointed the muzzle out. But despite his craning, there was no way he could see out the vent to aim.

"We could shoot out the main hatchway," I said, but no sooner had I done so than I heard the outside latch lifting. I leapt through door number one and skidded down the ramp that led to the outer door, hoping to jam it shut, but before I got there it was kicked open, swinging inward on its hinges. A dancing troodon jumped in, its sickle claws clicking on the metal ramp. I braced my rifle against my shoulder and fired into the thing’s chest. It was blown backward out the door by the blast, but a moment later a second troodon jumped forward to take its place. I fired at it, too, winging it. But I was sure that the Hets had more dinosaurs than I had bullets.

While I was reloading, the second troodon made it through the mandrill’s mouth, one three-fingered hand covering its wound. Klicks barreled past it, running down the ramp to the main doorway, trying to force it shut, but the arm of a third troodon scrabbled for purchase around its edge. Meanwhile, as I rushed to reload, the injured troodon that had made it inside scurried up the ramp and into the habitat. I followed it up. It tried to negotiate its way around the two crash couches to get at me. I fired both barrels into its torso. The creature slammed backward against our equipment lockers and slumped to the floor. The stink of gunpowder filled my nostrils.
